[@DC The Dragon]Yeah what robbie said. I think it's just a roundabout way for saying "Offence" and "Defence". Like boxing. You got sluggers, swarmers and out-boxers.

Sluggers- Big strong punches and heavy swings.
Swarmers- Pepper them with a bunch of quick shots and stay mobile.
Out-Boxers- Keep your distance, pick your shots and keep your guard.

EDIT: Mute now uses Tonfas and not katanas
