your point? patch wont make big difference if u play calamity or agony, is's general AoE nerf so only destro will sorc will be nerfed but small difference in your plystyle and i doubt dmg will decrease much, as for mara good thing that after beta i didnt started one only demolition will be stronger :/ few nerfed rest stay as it is now.
As i said its aoe nerf and next patch probably will make things more ballanced
