Range. People don't seem to understand that there isn't an "invincible" strategy for this game, if a stormcaller activates near you, and you don't have multiple teammates ready to take him out, you will die, the only counter is to get lucky with a shotgun or to be far enough away from him to land enough shots to kill him before he reaches you. The same can be said for arc blade and hammer of SOL. THE POINT OF THE SUPER IS THAT YOU HAVE A SHORT OPPORTUNITY TO GET A LOT OF KILLS EASILY. There should not be an easy way to counter a super.
