@Meddler A new event game suggestion Battle Royale

First time posting here.

I was thinking about an idea of Battle Royale style event game. If making a bigger size battle ground is not easy, we can play the current Summoner Rift map. 15 people on each side either blue or red. Instead of minions, each player champions become minions. 5 people per each lane and you are forced to march forward just like minions until you engage combat against another team. Just a basic concept so far. We can add few other rules here and there.
