Riot, have you considered the backup you are preparing might be a clue that role ranks are a bad?

So to my understanding, they are prepared to revert to the old rank system if they notice a large issue whether that be abuse of the new system or something else. They also are only releasing it in NA and KR so they can make sure it works.

Listen Riot, no one is asking you to innovate. Please consider turning the role ranks into a hidden mmr whilst keeping an overall rank. Do you understand how difficult recruitment threads are going to be for competitive players. Its gonna be some non sense like "Gold 4 mid, Silver Top, Silver Bot, Gold 2 Support, Bronze Jungle, Looking for team". I don't understand why you guys are so set on ruining your own game.

Please go back to making changes when there needed, not when you want to sell a skin
