Why not make it a 'what do you like about wow'? Would be more fun
But your thread, and I will comply!

- Quests, I allways hated em, the fact that you have to run around with your character instead of utilitizing it, meh! Quest helper helps, but still!

- Classes is waaaaaaaaaaaay too generic, I mean, everyone got basicly the same skills all around, sure class A's stun is used differently then class B's but its still the same deal.

- Instances, I haaaaaaaaaaate this concept, especialy for a pvp server. I'm sorry what? You say I cant follow that guy into a zone because it magicaly splits into two? What??

- Total lack of community, I guess this is a offspring of the instances, everyone is out doing their own thing.

- Quest caters again to a anti social style play because ALOT of them is a total !@#$ to do as a group.

- Itemization is generaly really out of whack, especialy when you consider wow only got 2 expansions, you went from having 10k hp to 35k++++ in just two expansions, could have been handled ALOT better

Now with all that said, ill go back to questing...
