If you could, would you go back to Wrath? and Why or Why not?

No because I find the average level people play at in cataclysm higher than in wrath. The increased dungeon difficulty coupled with CC and actually having to pay attention to stuff might have to do with that. In wrath the lolkids where king and could tell you to shutup, now they shutup and try to improve themselves due to peer pressure, or they just stay far away from you. Long story short: I've noticed a change in attitude.

From a raiding perspective: the cataclysm raids are way more interesting and notably harder than wotlk dungeons. Bar ulduar I guess, but never raided ulduar when it was active content.

In cataclysm I don't like that whole trash & cc approach. I much more prefer having to maintain aggro on 5-6 mobs and chain pull than having to cc all the time. I don't see what skill is required to cc either. I was hoping that maintaining threat in cata would be more of a challenge, but unfortunately it's not.

From a theme / look and feel perspective I absolutely love the icy/winter theme of icecrown & icc. In cataclysm I can't say I particularly like a zone/instance/raid besides the new updated orgrimmar and to some extend uldum. But then again, I'm not really interested in lore nor do I have a clue about it.

In cata we have 2 wonderful BG's, but Tol Barad clearly loses it from wintergrasp in my book. The rated bg's add a whole new dimension to pvp as well.

Questing: I hate the fact that bliz takes us by the hand and leaves us no choice in quest progression. The phasing totally blows but they seem not to understand that.

The fact that we can fly now everywhere is a huge addition to the game.

So ... no way I want to go back to wotlk. Too many good things in cata.
