LEAGUE OF LEGENDS COMMUNITY MARKET CONCEPT S6 OR S7

Hey Riot, ive been playing your game for 4 years now and ive also been playing csgo. And we apl know that csgo has a market where u can sell or buy skins, now aince the paunch of HEXTECH CRAFTING, maybe you guys should develope a independent market similar to cs but where u can sell things such as; Skin Shards, Ward skin shards or Icon skin shards. Then use the currency as RP where people can use or gain. Thanks for anybody who saw this post, and also alot of people have thought of this concept before, so im not the first.
