So I read a Mesmer trait in the changes, the trait gives quickness for 3 seconds when you interuppt enemies with a ICD 5 sec,For Thief the flanking strikes gives haste which means fury and quickness, but they dont say if its everytime you hit from behind or side, they dont show a cooldown, and I dont think they wrote it wrong either, so does that mean its haste everytime you hit from behind or side with no cooldown. My guess is it is everytime but you only get like 1-2 seconds.
