I'm not sure if the idea has been suggested before so i'll just post it.

Had the idea of having more costumes beyond armor recolors (which we could use more new ones anyways but that's not the point) like having the option of having a shield costume. Having one shields effect while having another ones appearance.

Also had the idea of different small things like weapon covers. Like attacking with a weapon but having it look different, (Candy cane sword with flourish/brandish/whatever effects. Whatever else there could be to cover guns and bombs. Maybe a toy bomb and a musket? Ha) and the ability to do other small stuff like changing the upcoming dash animation with some different options like a roll or slide something. < Small things that could add diversity but its probably too much to ask for. (And of course you'd be nickel and dimed for each one)
Small things. Maybe give the knights the ability to buy instruments and use them like they use emotes. Just bust them out and start looping an animation like they're playing them. Different armor costumes that aren't recolors, and new accessories. What could they be? Don't ask me I'm not a scientist.

For whatever reason i felt I had to post it here it is. Aiiro out.
