The xp lvls we get on cubecraft are pretty pointless atm. An idea to make them more useful could be that you got a custom cape every 10th lvl.
Maybe they just be able to equip the cubecraft one which will replace their own one and when they unequip they have their normal onethat would be cool, but what about people that alredy have official capes? or people that use 4d skins to get custom capes?
