I was just wondering this, since Chi Brew can't proc Combo Breaker, and gives slightly more TEB generation that Ascension, wouldn't Ascension look a lot nicer if you have the 2pc and ran at the Haste cap? That way you'd have more Chi generation from jab which means more Combo Breaker procs on Blackout Kick.
I know maybe when you get your 4pc Chi Brew would once again look very appealing, but how much does Combo Breaker do for us? I'd imagine a lot considering the huge damage boost.
