Hi all, our group just started doing A5s and we're barely getting by on Faust, and hitting enrage at around 10% on hummel. I've been popping B4b for Faust to help us get Faust, but I don't use any other cds (just reload after a 5 ammo pre pull). I use rook.

How are you guys optimizing your cooldown/ammo for this fight?
