pre-50: whenever it's up and you've got 5 stacks

50 and beyond: single target = Infuriate -> Tomahawk/Overpower -> Unchained -> HS -> Brutal Swing -> Maim -> IR + Berserk -> Storm's Eye -> HS -> SS -> BB -> Fracture -> HS -> IB -> Brutal Swing -> Maim -> Storm's Eye (MT only, can replace IB with Fell Cleave and enter Deliverance before Fracture if IB isn't needed)

multi-target = Unchained + Bloodbath -> OP -> IR + Berserk -> OP spam
