A way to kind of fix mirrored bans.

Say one or more players ban the same champions well there can be something like a mini-game that follows after. They could each roll dice (something that works and looks similar to what happens when you combine skins) and whoever rolls higher gets to ban a champion in exchange for the one they previously banned which follows on until all players with mirrored bans contest for another pick after this the picking phase begins.

Maybe this is the wrong forum section or w/e and if it is my bad but I'm just throwing some ideas out there anyway (maybe someone already came up with this IDK.)
