a new Game map

I dreamed about this game map today. I woke up and I had to share it. I dreamed I was talking to someone from riot and telling him about my idea .. of.. a coliseum between 8 players, free for all. so they can pick any champion. they respawn around the coliseum at level 18, full abilities. they only have one chance to buy with a certain amount of gold. the winner is the last man standing. it should be a quick little game just for fun to destroy each other really quick like in team fights. maybe we can do it like urf when they don't use mana and the abilities are all crazy. I wonder what the community thinks. also I don't know if there is a place where I can put my idea of this new game so riot reads it. thanks for your time.
