This is the only roaming super WITHOUT any visual aura indication. Spectral blades, Fists of Havoc, Nova Warp, etc. all have a visual body aura that lets you glow, yet it is incredibly hard to determine if a Hunter is in its Storm's Edge super or not, unless you see them use it actively. That aside, there should also be a "knife weight" to the attacks, so you can't throw the knife on long ranges without accurate aiming. Make it a ballistic projectile, not a hitscan-teleport attack. As same as a Dawnblade has to aim on range by aiming higher to hit, the same a Hunter should have to with its knife super.
