When I use Blade Storm, my character very clearly lifts his lightsaber, lowers it, lifts it again, pauses to consider the ramifications of his actions, then finally executes the ability. Is this because of the parry delay? I've been watching this ability closely lately and it seems to work alright when I'm 10 meters away. Of course, that hardly ever happens, because I'm a melee class.
It would be one thing if parried blaster bolts went back and hit their shooter, as others have suggested.
