Orcish Fury strength boost should be on a 1 min timer instead of being instantly dispelled as soon as you go over the 10, 25 or 50% health mark.
OFC if the player was still below the health mark then when the timer expires (or if he goes below a new health mark) then the timer would reset with whatever strength boost he is due.
This would make it much more useful and people might actually try to fit it into their builds instead of just using it to get screenshots of 100+ strength.
