It's good but the bar is no longer T6, which is does great at - players want to get to the highest grift possible or at least 35+ and when you hit that level there is only 1 option for builds from each class. (some might have two but technically one excels the best)

Crusader - Stampede
DH - T6 turrets
Wizard - Fire set.. forgetting the name.
Monk - Sunwoko
Barb - Raekor's
WD - pets sort of.. or their dot build but it just doesn't scale as good as the others.

Currently the most powerful and also the easiest to play is definitely the demon hunters.
I got my wizards to be comparable but in order to really maximize DPS there is just somehow too much stuff on the screen and I get bandwidth lag, my PC can handle it but the game isn't able to and everything stops moving and jitters.
