But Nightstalker is fast and agile, with more useful perks. I mean, think about what Shadowjack is now. All it really is is a boundary they placed for invisibility timer, that you can lift. It doesn't change the playstyle, like other perks and abilities, it just... it's the Stand Asides for Striker, and how often do you see those being used? But we accept it because it affects three perks. I'm pretty sure they couldn't think of another good perk and decided it would be good to put a timer dial on a perk they thought might be OP. And honestly, anyone who decides to use a perk slot on Bladedancer's very conditional invisibility should get the full timer without Shadowjack. Your perk slots are as important as which Exotic you use.
