Skin trade system?
Not sure if this would be the best place for this, but Mystery Gifting has given people tons of gifts. Some people already have the skin they want to use all the time. Some people have all of Teemo's skins, or all of Lux's, while one of their friends might want Sorceress Lux Skin, and the other friend might want Maid Nidalee if the other person doesn't want it.
System would only be between friends, who were friends.
What are your thoughts on the idea I came up with, ideas to add on, or if it is even logical at all for Riot?
