TBC made WoW far less enjoyable for a large number of people. I will agree whole heartedly that I had WAY more fun raiding at level 60 than I did at 70. The reason - raiding was far more casual friendly before the expansion. The best way I heard it put was that half a raid of semi-hardacore players could usually carry the other half (as long as they were moderatly skilled) through most raids up to and including BWL. You could run through MC, ZG, and BWL in a single night in about 3-4 hours.

Now they made raiding so stupidly complex that unless you have an enitre raid of experts who do nothing but devote their entire attention to the game for 4+ hours at a time several times a week you aren't going to get anywhere (being in a TBC era raiding guild I have experienced this repeatedly). Watching good friends who had real lives and used to get on on Wednesday and Saturday night to blow through ZG + Ony and MC or BWL start dropping like flys (including two of my best RL friends in the last month) really killed my enjoyment. The raids in TBC just seem to make normal people angry and bitter since it is such a chore and huge time investment to get anything down, whereas in pre-expansion raiding people used to have fun.

I just canceled my account, I wont be coming back hopefully. Ever since WoTK was announced people are getting stressed out and crazy since most of them think TBC was not what they had expectected or wanted in an expansion. TBC killed the enjoyment of the game for casual players and I don't think Blizzard can do anything to fix it at this point.

I am currently looking for something to eat up my free time until The Orange Box comes out next month. Dark Crusade is on Steam for $20, which looks like a lot of fun, and judgeing from the Galactic Assault demo it will be pretty enjoyable as well. I might even break down and buy Bioshock in another week or so once they get most of the major bugs worked out.
