You're not supposed to use 2H on the PA, you're supposed to use it on the CD follow-up. That way you get even more style damage from it AND there is only a 1.5 swing speed delay between PA and CD.I always felt considerably weaker on my SB on Phoenix than Infs and NS's. The only thing that allowed me to beat them was higher RR.
The lack of stuns is killer, especially when Infs get that 9s stun off evade.
2h PA was never worth using on Phoenix due to the huge delay between PA and your next swing and crap 2h damage. Unless 2h damage is rectified here, it will remain gimped.
