I don't know about you guys, but arc blade is one of the more underpowered supers. Sure it's fine if you are in close quarters and other players can't escape, by most of the time this isn't the case. Players can easily jump back and shoot you. That's why I think activating arc blade should also give you a shield that triples your defense. This will actually make Arc Blade an effective super instead of a joke.

arc blade Should be able to send a shock wave across the pvp map strong enough to kill an enemy player anywhere, and cause their character to delete. also drain the shield of friendly targets.
