i like the questline where the hozen falls in love with the undead :D
My favorite part of Mists is that you absolutely have everything at your fingertips. Pet battles, PVP, Raiding, Tons of quest and hours of non stop fun. I love everything about it. Can't just pick one :). I love the Scenery also it's beautiful.
The environment throughout the whole continent.
Pet battles obviously!
I like the rare spawn hunting and treasure hunting, need me that Relic Hunter title. >:3
Dailies, factions and zones. That are fantastic! And the music is so beautiful! I really love this expansion. The best one, so far!
All the new mounts are pretty cool.
Favorite part of MoP you ask?Running old instances and AoE looting. Also levelin' up those new pets. Gotta catch 'em all!
Pet battles !
Everything is great about mop, really like it :)
Pet battles, love it, I just love being able to do more with my pets now xD
The new dungeons, as short as WotLK with the flare of BC and Vanilla.
The veiled stair :D specially the black market
The warrior tanking, insted of just spaming Heroic strike or Cleave you must use it more wisely for dmg reduction. And ofc the dps on some fights (a).. I think the raids is funny two, me and my rls have downed 6/6 MSV and 3/6 HoF and I'm always eager to raid becuse it's more challenging and more funny fights, especially Elegon. We struggled alot on him but never lost our hope :)
I think my favorite part of Mists of Pandaria so far are the Farmer Yoon's grounds. I find it very useful to be able to get 16 Mote of Harmony a day. Oh! And the cloud serpents are awesome too! Oh! And the monk's Zen Flight form, and the new raids, and... I think I'm gonna stop now... :-)
I really enjoy the story in Pandaria. AOE looting has also been a blessing :D
Hmm that is a hard one. For me it would definitely have to be the amazing artwork of Pandaria :3 That and I LOVE the lore that comes with it, especially the Klaxxi lore! :D
I love the fact that you get to do a lot of dailies to rake up gold and reputation. I also love the fact that now all mounts and pets besides pvp are account wide. I have loot pets and mounts so my money has been well spent.
