The escape artist perk for the blink strike in the blade dancer subclass only works about 50%(+-) of the time. For example; when I am attempting to revive a friend that is swarmed in the Nightfall, I will go invisible and blink strike an enemy to extend the invisibility time, But about half of the times i do so the escape artist perk just doesn't work. The blink strike will activate but after i hit the enemy i do not either become or return to invisibility. is anyone else having this problem?
