I find WoW to be very anti-teaming. I think the non-group drops show this. What few grouping items they had have been removed or seriously weakend ( most non-instance elites were eliminated ).
What is worse now is that all of the instances prior to UK do not prepare you for how hard UK is going to be when you get there. Kara is easy.

I'm feel like the people who wrote WoLK never played WoW before. The mount quests, the way things are looted such as kick before loot or talk to the dead to loot or just plain overly complicated looting ( mind control a pet to loot, mind control a pet to kill something ).
I kind of found pre-wolk questing to be 5x the fun to have a team and WoLK questing is almost like having 1/5 the fun to have a team.

WoLK pvp sux, WoLK rewards from heroic badges sux. Having everything you have worked for so hard for invalidated every time they spit out a change to the game sux.
