All For One/King of the Hill Game Mode

Me and my friends tend to fight over who gets to play new champions, and with Jhin just around the corner, things are going to get heated once again.

I don't know if anyone else has thought about this, and I apologize if they have, but a game mode where everyone has to compete would be fun as hell. I'm not sure how many players could be in this game type (maybe 5-10), but it'd be kinda cool to see something like this on League, with the added addition that me and my friends could settle who plays new champions every time they come out.

Let me know what you think. And direct me to a post that's gotten more attention. I'd like to know what people think :)
