I updated spreadsheet with changes relevant to our "discussion" ;P
What got changed in spreadsheet:
I added Winter's bite to the rotation since it now applies bleed. Two casts in pure AT, and one cast in shortbow+AT variant. Because of 1/2 cast time, i took away two (1/4 ct) ricochets for every cast of WB.
I raised physical damage of physical strikes of Poison Volley and Quick shot
Raised condi duration of poison volley
Added pet bleed that occurs after shooting cripling shot (assuming 1300 condi damage on pet)
