Bestial Fury is completely broken at the moment.

a 5 point combo headshot gives you 54secs 5% dmg
now fire off a 2 combo headshot....yep thats right your 54s now just became 12secs.

lesser combo headshots are over writing higher ones, need to finish off a target whilst under bestial fury? dont use headshot at the moment, your removing your own buff.

not sure how this made it through beta, did anyone actually test anything?
