Didn't notice a thread so lets go with this. *puts up rage shields*
Personally:
Bams - shafted, made more support oriented (hope they change them some more in regard to the raging)
Wh - better dps, but kinda odd (need to see more of it to have more of an opinion)
Mechs - better mobbing dps, better(?) bossing dps, HEAL BOT STILL DOES NOT HEAL 50 FREAKING % HP.
