Maybe do it like monster hunter. Each gear set is made to combat specific monsters, and you can mix and match to get specific skills for whatever you want as opposed to only one purpose. Have gear slots for bonus points. Maybe you could end up [b]doubling[/b] your roaming super time, but take a shit on your recovery and armor. Sure you could use spare shots and lighten/negate that loss, but your friend has multiple benefits (maybe not as good as double roaming time/attacks) and little to no drawbacks if they're smart. It'd make trying for specific gear that much more important, like reload gauntlets or extra shotty ammo chest piece.
