Barb nerfs are imo nothing, damage from bear stance was really minimal and hardly significant. You just can't use now all spiral/deathgaze/stampede as 1 pointers, instead need 5 more points if you want to "Unlock" the skill (btw much better way of limitng trees than making entire tree locked, because you can still mix them if you sacrifice something).
I'd say barb nerfs, at least melee ones are so minimal its gonna be hard to even notice the difference.
As for sorc, it does look weird. I'm guessing that debuff nova is supposed to be main compensator for ice elemental aura removal, because honestly, running with 400k def cold sorc was wayyy better than having more life from fire tree, it isn't even close to making up for loss of that defense.
I guess we have to deal with that caster sorc can't be tanky.
