I don't get it why donation always have to contain OP or not fair rewards, i mean add some own costume unique masks without any stats or like with some active skill for cp pot's creation, but make the masks look really good, also some colored title or some special transforms, i mean if you add donation with unique things that only good by the visual look, it wont hurt anything and maybe some people who like rpg or just like your server will donate for this stuff.
