I would absolutely love if they gave character customization an update and more options. I build characters for fun, so the look can often be a driving factor behind them.
As a side note, it would be nice to either get options for either hiding pads like shoulders, elbows, knees, and the thigh pads or getting invisible costume part unlocks. They all look ridiculous and are made all the worse when they're clearly floating two to seven inches off the player model.
