Because a high aim assist, fast travel time, long distance super needs 7 shots. Not that hammers need seven, but... The armor and health regen don't bug me. The proximity detonations and duration do. Tone the duration back five seconds, less hammers and less roaming. Lower the proximity detonations so you actually have to hit with your hammers. The duration is also something I have a problem with on Stormcallers, but I'll just shush about those now...
