isn't it supposed to send the opponent into a 'bubble' and like keep them in the air for awhile?...maybe it could be like;
You throw the grenade. When the grenade hits the ground/opponent it breaks apart causeing a circular waze(the center of the wave would be where the grenade landed) and whoever was cought in the 'wave' would then be sent into a 'bubble' and thrown into the air for 10 sec, but the bubble would shield them from any/all attacks, and when in the bubble they can't move or shoot.
it should be like that
