Currently the Hedronic Arc skill is really really really worthless using it and consuming the 5 charges you might have saved up.
Currently it works where the first hit on an enemy makes the AOE off the center of the enemy ONCE. If you punch a different person it does it off them ONCE. It should do the AOE pulse EVERY punch.
Additionally Pounce, 5 charge version should just be stronger. OR instead of shoving people you just stun them. 100 damage to shields is half useless due to either the enemy not having shields at all, or you broke their shield with normal attacks.
Also I kinda feel like shield piercing is pointless on his passive, just give him like a 10% fire rate buff for keeping charges. Or better yet! Sprint / movement speed increase!
