There is an overabundance of AOE blind on random abilities. Blind is a powerful, if not, one of the most powerful debuffs in the entire game.
One of the biggest reasons ranger and warrior are doing so bad in SPvP right now is because while before pre-feb, they were perma blinded, the second they were able to land any damage it nearly 1 shot the person. You also added explosive entrance blind which is nearly perma blind vs holo's(on top of blind grenade).
Please consider lowering the durations of all blinds, removing it on some skills, or just making some of it single target instead of AOE.
