i think that it would be really cool if you could trade out your legendary sword (arc edge, solar edge, void edge) for something small but has a huge punch. the dualstorm, the voidslicers or the sundancers names can be revised but withe these you would attack with each bumper to slice and press both at once to unleash a whirlwind of havoc on your enemies and the would increase speed when equiped but you can always get your old legendary sword back. but its just an idea.
