Weird Game Mode Idea

Free for all. No, not Battle Royale, something different, but similar. You have a mini nexus, and one tower guarding it. Minions spawn from your mini nexus and follow you around the map. Why you, and not lanes? Because there are no lanes. It's a Dominion style map and it's vs. 4 other players. The goal is to gather up your minion army and war against other players in this map. Whenever you knock out another player, you gain a super minion with the next wave. In the middle of the map, their would be a rift herald, but mega buffed, so it has like baron level hp and buffed damage so it isn't that easy to take down, especially with all the other players around you. Feel free to pick whichever champion you want, of course champions with wave clear would be insanely good but someone like sivir would still get wrecked by someone like kled if she got caught out. There would be fog of war so wards would be vital to seeing enemy movements, when to defend or attack etc.

I literally just came up with this idea, I know there's a billion and a half things that need to happen before this game mode is even conceivable but a strategy, war-like, mode would be pretty fun [slayer-jinx-wink]
