When Regrowth crits, is the HoT component increased as well as the direct-heal component?

Comment by 3996

Regrowth is a powerful healing spell, however is relatively mana inefficient. Use this when you want to "forget" about a player for a bit or when you need to keep a constant stream of healing on a person.

One situation where Regrowth shines is in the Vael fight in BWL. Just spam this - it's great due to its shorter cast time and its constant healing.

Comment by violatus

Very nice HoT spell especially at higher levels. You can use it before aggroing a foe so that you keep your health high during the fight.

It's a huuuuge mana hog but very nice healing spell to use in PvP because of its fast casting time (well, faster than Healing Touch).

Comment by malum

With moonglow, it is now 614 mana. This makes regrowth the second most efficient heal for a druid, after lifebloom. Nice buff!

As it stands (calculating averages with criticals), a restoration druid should find this to be their number one skill now for their first cast, it used to be quite mana inefficient compared to other skills and mostly for emergencies // focus healing, but with the new buff this skill is going to be pretty amazing, especially when I already am forced to spam this skill for certain fights (Such as Naj'entus, where it is extremely important). Expect to use this spell as frequently as lifebloom come 2.4.

Comment by Robyn

It looks like Blizzard has finally recognised that all healing classes do need a Flash Heal style heal with a rapid casting time. With the latest few changes the efficiency still looks bad if you're over-writing the HoT, but with Imp Regrowth and the average bonus heal from its frequent crits it starts to compare quite well with Flash and Lesser Healing Wave.

All of which makes druid healing just that bit easier for Resto druids.

Comment by MasterOfDisguise

Regrowth gains ~100% of your Bonus Healing, and is broken down into two parts:

The direct part of your heal gains ~30% of your Bonus Healing
The HoT part of Regrowth gains ~70% of your Bonus Healing

And since I believe the coefficient of DoTs are broken down evenly over time, each tick of Regrowth gains 10% of your Bonus Healing (since the HoT ticks every 3 secs for 21 secs, which is equal to 7 ticks)

An altogether decent spell to cast by itself, talented and glyphed this spell is a power house.

Glyph of Regrowth + 20% initial heal
Improved Regrowth (Talent) + 50% critical chance, triggering Nature's Grace and Living Seed
Nature's Splendor + 6 sec. hot duration (27 sec total)
Mana reduction talents from Tree of Life and balance (Moonglow).
And of course, it can be made instant with Nature's swiftness and be consumed for Swiftmend.

I haven't looked to closely at the wrath idols, but I'd expect there to be one to improve Regrowth somehow.

Comment by manicmania

The spell power coefficent of the direct heal, and heal of time is as follows:
DH-approx 54%(64.8% with Empowered Rejuvenation)
HOT-131.6% (157.9% with Empowered Rejuvenation)

Comment by Aisenfaire

Nourish and Healing Touch cannot match a properly specced and glyphed Regrowth for a PVE tree in terms of HPM, HPS, initial heal, and added HOT.

Regrowth has:
- a 50% chance to crit (Improved Regrowth), which will proc Nature's Grace and Living Seed
- heals for 20% more if Regrowth HOT is still present on the target (Glyph of Regrowth)
- HOT benefits from Empowered Rejuvenation, Genesis, and Nature's Splendor

which unfortunately cannot be matched by Nourish.

There is still an optional place for Nourish as a small heal to avoid overhealing and waste of mana, but it definitely cannot replace Regrowth as the big heal.

(I do not mention HT much, as glyphing and speccing for this is primarily for PVP, which is a different concern altogether.)

I'm going to be doing a more complete breakdown of the healing per mana and healing per second of Druid single-target large heals. For this consideration, I'm mostly looking at burst Hps (heals per second), so I'll be ignoring the HoT portion for calculations.

Regrowth Rank 12
29% of base mana 40 yd range
2 sec cast
Heals a friendly target for 2234 to 2494 and another 2345 over 21 sec.
Average Base Heal = (2234 + 2494)/2 = 2363
Base mana at lvl 80 for a druid: 3496
29% of that is 1014 mana, before reductions from talents.

Coefficient Approx 53.90% (64.68% with Empowered Rejuvenation)

Talents which effect HT:
Moonglow 9% cost reduction
Master Shapeshifter 4% increase healing (while in ToL form)
Gift of Nature 10% increase to all healing
Empowered Rejuvenation 20% increase to healing coefficient for Direct Heal and HoT portions.
Tree of Life 6% increased healing to everyone you can reach with your heals (45 yard range). Also, 20% further mana reduction
Improved Regrowth and Natural Perfection for 53% total crit chance increase and Nature's Splendor for a potential 0.5 cast time reduction.
Also, can be used with Nature's Swiftness for an instant cast.

Can't forget the Glyph of Regrowth +20% healing done for the Direct Heal and HoT portions if a Regrowth HoT is still on the target.

The case that I'll be looking at is maximum burst Hps. Specifically, I was contemplating a build that improves healing touch to be used as a backup after getting a Nature's Splendor proc from a Regrowth crit. Haste effects both spells evenly, so I'll be disregarding haste. Crits will play a big role because we're counting on Nature's Splendor for big bursts. I'll be doing several tables based on the druid's critical chance.

Talented Mana Cost:
Base: Moonglow: ToL: Both (multiplicative/additive)
1014 923 811 738 / 719
I'm pretty sure 738 is the value off my Druid on live with Moonglow 3/3 and in ToL form, so I'll be using that value.

Base healing (Without considering Crit)
+Healing Amount Healed HPM HPS
1500 4042 5.48 2021
1600 4120 5.58 2060
1700 4199 5.69 2099
1800 4277 5.80 2139
1900 4356 5.90 2178
2000 4434 6.01 2217
2100 4513 6.11 2256
2200 4591 6.22 2296

Considering crit, with a base crit chance of 10%/15%/20% and +50% from talent. HPS and HPM columns reflect a 60% crit chance
non-crit 60% 65% 70%
+Heal -Heal -crit -crit -crit HPM HPS
1500 4042 5255 5356 5457 5.48 2021
1600 4120 5357 5460 5563 5.58 2060
1700 4199 5458 5563 5668 5.69 2099
1800 4277 5560 5667 5774 5.80 2139
1900 4356 5662 5771 5880 5.90 2178
2000 4434 5764 5875 5986 6.01 2217
2100 4513 5866 5979 6092 6.11 2256
2200 4591 5968 6083 6198 6.22 2296

Note, all values are the average amount healed. Average amount calculated from:
(Base heal * non-crit chance) + (Base heal * crit chance * 1.5)
where 1.5 is the crit multiplier.

Now for a subsequent cast where the Glyph of Regrowth kicks in. Also, the cast time will be somewhat less because we just finished a Regrowth cast which may or may not crit. The heals per second (HPS) columns reflects a 60% crit chance on the previous cast (for an average cast time of 1.7s). The heals per mana column reflects the 60% crit chance for the current cast.

Average cast time derived from:
(base cast * non-crit chance) + ((base cast - 0.5) * crit chance)

non-crit 60% 65% 70%
+Heal -Heal -crit -crit -crit HPM HPS
1500 4850 6305 6427 6548 8.54 3709
1600 4944 6428 6551 6675 8.71 3781
1700 5039 6550 6676 6802 8.88 3853
1800 5133 6673 6801 6929 9.04 3925
1900 5227 6795 6926 7056 9.21 3997
2000 5321 6917 7050 7183 9.37 4069
2100 5415 7040 7175 7310 9.54 4141
2200 5509 7162 7300 7437 9.70 4213

That's a lot of spreadsheeting. For the time being, I'll leave my conclusion at this: 1800+ spell power unbuffed and you're looking at 4000 HPS (before accounting for your haste rating or Wrath of Air 5% spell haste!) from spamming regrowth at nearly 10 HPM. Buff food, a shaman totem and maybe an elixer, and regrowth spam is just plain retarded.

Eventually, I will make the comparison between plain regrowth spam and Regrowth - (Natures Splendor proc) 2.0 Sec HT cast - regrowth decisions. I have a hunch that the reduced crit chance on HT will kill the HPS consideration.

Edit: Good grief, I did all that work and now they're changing a key talent. (3.1 patch notes, taken from mmo-champ) I'll revise this shortly, when 3.1 has a known date.

Improved Regrowth (Tier 6) renamed Nature's Bounty. Increases the critical effect chance of your Regrowth and Nourish spells by 5/10/15/20/25%. (Previously increased just regrowth crit by 10/20/30/40/50%)

Comment by Pythagoreant

This is druids' quick, expensive heal.

In Cataclysm (as of 4.0.3a), all healers have the following types of heals:

Quick, expensive heal: 1.5 second cast, very high mana cost, high heal value.
Inexpensive heal: 3 second cast (usually talented to 2.5), very low mana cost, low heal value.
Slow, big heal: 3 second cast (usually talented to 2.5), high mana cost, very high heal value.

The mana costs differ very slightly between classes. Two of them have the quick heal cost more than the big heal.

Priest
Quick - Flash Heal
Cheap - Holy Word: Serenity
Big - Heal

Big - Healing Wave

Restoration druids in Cata:

Note that Insect Swarm is considerably cheaper than Moonfire or the very expensive Regrowth. Use your free haste trinket (1-minute cd) from Nature's Grace wisely while you wait for Tree of Life (3-minute cd) to become available.

Comment by wye43

This spell is a tool, it should only be cast during Clearcasting, and to trigger Nature's Grace.

Comment by Nazgren

This spell can trigger Harmony because it's technically a direct heal and a HoT. Tested 10/19/11 in heroic ZA.
