While I do agree that some of the decisions were poor, I wouldn't say that Cataclysm as a whole was done poorly. The new zones and the streamlined quests are so amazing... I don't mind doing it all over again on another toon.

As for healer mana shortage, all I gotta say is... That's pretty much what the playerbase wanted. You can essentially make the tanks and DPS easier to die and achieve the same effect, but that's contradicting their philosophy of trying to prevent spiky damage. Players wanted more challenging content, and that's what they got. And I'm sure a lot of us already /ragequit.

As for the imbalance of Tol Barad... In my last server (Detheroc), it was literally once in a purple moon that we had Wintergrasp, since our server was so horde-oriented. And now, in Medivh, the horde literally never had the snowy fortress. While these outdoor PVP zones might be fun for properly balanced realms, there'll always be a faction that's getting screwed over, and not even tenacity could solve it.

Don't get me wrong. I still think Tol Barad is unbalanced as hell. But just as Wintergrasp never got a proper repair for it, I doubt there'll be one for something that's... well, THIS screwed up.
