I still think the Death Knight T10 looked really awesome, but by the time I saved up enough Emblems of Frost, Cataclysm came out and now there was no need to buy any t10 items for my DK.
Oh, so many good choices. Bloodfang was fantastic on Rogues, and I like the Dreadnaught on Warriors.My favorite, though, is the Lightsworn Plate. Not the Sanctified, though I enjoyed the Ulduar hard mode bosses, the look of the regular Lightsworn Plate was great; evocative, had the Paladin skirt, and was bright white to go with the Paladin's look and style. Granted, I have a love for the Tankadin, but I really think that the Lightsworn Plate was one of the best designed armor sets in the game, even better than Judgement, Paladin Tier 2.
My favorite Tier was def the rogue tier 2, bloodfang. However the main reason I loved that tier is it looked great with the nightslayer pieces. Those two tiers meshed so well together that when you saw a rogue stealth wearing that stuff you knew you were in trouble if he was coming your way.
Hunter T4 set. The Demon Stalker Armor - Demon Stalker Armor
Warrior T6 hands down best set ever..Especially when you add in the Shield from Illidan, http://www.wowhead.com/item=32375.Still have it in my bank, and bring it out to reminisce of the good times of TBC.
Paladin tier two judgement, The art on it alone is enough to make any class go "I want that!"it was also the driving force behind me making my own blood elf paladin one year later
Warlock T6 had to be my favourite. It just looks so fierce and brutal, and the wings just look awesome.Look at it compared to what we have now... Who would tremble in fear at the eleventh tier? But tier 6... One just had to bow down at the superiority and awe of it!
Hunter's Warpstalker, for the pet heal set bonus
Tier 2 Druid set. Why? Who doesn't want to be a moose?I mean really, it gives you an excuse to run around (in a skirt, mind you - big plus for men!) and do moose calls!"Moooooooooooooooooooooooose!"
Rogue tier 2, Bloodfang set. Rogues looked dark and scary, dark red and black sneaking around. looked amazing
I liked the rogue tier 5 gear. Not only because it was the best gear I acquired in BC, but it just looked deadly.
Malefic Raiment Warlock Tier 6 was the absolute best tier of gear and my personal favorite. The periodic proc of the demonic wings was just priceless.
Warlock Tier 8: http://www.wowhead.com/itemset=-86#It looked so evil! And Ulduar was Awesome!
Aw man... Priest Tier 12 looks effin awesome man. Having the white cover and the flames spewing out really fits into the firelands idea. I was just looking at the possible tier 12 set piece procs and I think I jizzed like three times in 5 secs...
Mage Tier 6, the Sparkplug set!
The eye patch on the hunter really makes it stand out for me. I'll vote the hunter t12. The mask makes it really stand out from the others.
Warrior T6 - by far the most badass tank set in the game!Couple it with the Bulwark of Azinoth and POW - A tank that LOOKS like a tank - literally :D
I'd have to say for me it's T6 for Shamans, the overall blue look with the thundering shoulders => <3
Paladin T2, hands down. Just take a look at Judge Malthred. C'mon.
My absolute favorite tier set was Pally Tier 6, followed closely by 4. To me, it (they) screamed warrior of the Light. Not really a huge fan of these content themed armor sets. Make me look like a battle-priest dag nabbit!
