I actually would love this to be a thing mainly because I like using lightning grenades to block corridors or hold down an objective. After shock is great for cleaning up. One time in trials a killed a team with fist of havoc. I danced since it was the winning round. The sunsingers self rezzed, killed me and started tea bagging. My after shock killed him before he can revive anyone. My team mate revived me and I proceeded to dance.
