I appreciate someone defending blinking because outside of shotguning, blinking is very difficult to use right, and ive been doing it since week 1. The issue as I see it is the bladedancer subclass. On a warlock, theres about half a second of down time after the blink but with a hunter that has the quickdraw perk on, that period of blindness as you put it doesnt exist. That skill tree perk needs to be removed if that subclass is going to have blink or at the very least, the two shouldnt be able to be equiped at the same time.
