Back for cataclysm, few questions

[scarisen]

Heya. Lost my old account for mmo, but I'm coming back to the game after a few month hiatus for a training program, but I'm done with the regimen, and I'm about to come back to the game. I have a decent amount of characters accumulated, and am wondering what to use as my new main. I have the following classes with experience with (in parenthetical)...

80 Combat rogue (full ICC/LK)
80 Warrior Tank/DPS (full ICC)
80 Bear/PvP tree (Full ICC for bear)
80 Mage (T9)
80 Huntard (T9)
80 DK DPS (t10/t9)
80 Healadin/Tankadin (t10 for both)

All on Draenor-US. So atm (I realize with the expansion JUST coming out, some shit is going to be buggy, but regardless) is there anything super broken? I was really enjoying bear before I took a break, but when I was reading, there were allot of problems with bear tanking.

So, TL;DR: Any super broken stuff atm? Anything looking really fun? Any suggestions as what to use as my new main?

Play what you want too, play all the classes you have and see which one you like the best.

For you new main I was going to suggest Lock but you don't have one .
