You do realized that rapid fire is 15 seconds. So you mean to tell me, your gonna pre pot, pop rapid fire to so call get "frezy stacks" and pop Bestial Wrath afterwards when pre pot has 5 second left. God damn your pro, why didn't I think of this sooner! In addition to your oh so awesome opening rotation, since rapid fire gives "your pet haste", it would still be optimal to use BW during rapid fire so he can attack faster during BW and do more damage!
Plz stop posting, your confusing yourself and the community of hunters that read these forums
