With the Nighstalker Subclass, when you became invisible after a Shadow Step or a Smoke Bomb, enemies can still hit or chasing you for the first second like you're still visible. That's pretty annoying 'cos invisibility last 3 seconds with Shadow Step and 5 with the Smoke Bomb, so it actually works for 2 or 4 seconds at all. I think it must be fixed to grant to the Nighstalkers a full and correct advantage from Invisibility.
