I do suggest going to cryo3>kino3 knowing that the nerfs only affected team battle. i do think that its also pretty hard to do the full cast Icewall PP combo in pvp(barring 1v1) as the opponents wouldnt let you finish the whole thing.
Necro on the other hand still has tons of bugs affecting them. Im not too keen on sorc and necroes though so you might have to check more on them.
