I've been a Bladedancer main since the early days of Destiny, in PvP at least. Over the course of 2.5 years, it has seen nerfs to the following: Arc Blade damage Arc Blade duration Arc Blade swipe super usage Arc Blade hit detection (now fixed, kind of) Arc Bolt Grenade damage Arc Bolt grenade radius Skip Grenade damage Skip Grenade tracking duration Skip Grenade -1 tracker Flux Grenade magnetism Blink distance Blink preparedness time (x2) Blink cool down Blink -1 recovery Blink removes HUD Quick Draw ready time (x2) Blink Strike range Blink Strike Escape Artist activation time Blink Strike Backstab activation window Blink Strike Fast Twitch cool down Stalker activation time Hungering Blade health regeneration The only skill perks that haven't seen a nerf are Showstopper, Fleet Footed, Shadow Jack, & Encore. Staggering, really.
