Skin Trading

As an avid League player, sometimes playing the same champion over and over again can be immensely boring, so in a tactic to counter that, one may purchase a skin. They make the game a lot more fun, but at one point or another, the skins that you have on your champion could be boring, or the champion could get a huge nerf, in which you may not play as well with that champion like you did before. BUT if we could trade skins, other people can give skins in which they don't want or need anymore to others, like trading in steam, making League, overall, a more enjoyable game to play.
