For 3.3, I am looking forward most to the random dungeon queuing system, which will greatly increase the ease at which you can find 4 other randoms who are just as masochistic as myself to pug heroics. As a die hard Warrior, I am also eagerly awaiting the "Massive" changes being made to warrior :). Oh the joys of the new quest tracking/upgraded Blizz map I like not having to be addon dependant for menial tasks(WTB Sizable Zone Map). Ultimately tho, I am just looking forward to new content. Ulduar was alot of fun to go through, ToGC wasnt inventive enough, and rather dull. ICC will be a breath of fresh air.
