I'm fine with the nerfs, as long as they rebalance monsters too. Bring the skills in line so you don't have obvious great and shit skills next to each other (make them all "mediocre" or rather a similar power). Then all they need to do is lower monster HP and damage after the balance pass and suddenly every build works well again.

The nerfs hurt on paper, but they don't have to if the rest of the game gets a rebalance too.
