oh yeah, the warrior changes look great! i hear it's more great for prot and arms than fury, though. but i wouldn't know, i'm not much of a plate dps person. :( rogue, warlock, and druid are my mains, although i had a priest, shaman, and paladin at cap too (hello everyone, i'm doc and i'm a recovering altaholic...)

and i'd say that fire mages are better on mana now than they've been in the past! still really reliant on luck, though. all those abilities that rely on crits, it can be awful when you go a long string of hits without procs. but in general, fire and arcane have been pretty close in pve for the past year! which is something the other pure dps classes can envy, haha. but yeah, when i played a mage for a little while, arcane was always my favourite. the changes in MoP look like they're really going to shake things up, too (like their rotation, which... needed it...)
