Alright so it's pretty straight forward suppressor grenades currently do not disable a blade dancer mid super (it works correctly against golden gun and radiance). It did function correctly prior to the exotic weapons buff. I'll retest this with a friend in rumble just to verify but as of today I've chucked this plenty of times while a blade dancer activates their super (on the side, directly beneath their feet, even pegging them and letting it blow up on their face) and nothing happens they do get the icon above their head showing they're suppressed but the super is still active.
