A Chaser Game Mode

So I always had this crazy idea how league is always defined by one game mode which is PVP 5V5 , which is good to stick to what you know but it doesn't always feel like the best thing to do is to play a tryhard 5V5 game where everyone is intense, and when you try to let loose for a bit Aram sounds like the answer but its still a 5V5 game. So the other day I got this crazy idea about a game mode of a chaser one player chasing the rest he is level 18 full build and the rest only have boots, the chaser is picked randomly out of the 10 players every round and the last standing wins. I know it's a bit crazy but just think how amazing a game mode like this would be where your main goal is not to get caught while you have no vision and try not to run into the full build monster which also has a countdown if he doesn't get anyone before then the round restarts with someone else being the chaser and picking the champion would mean you have to pick someone good at chasing and running. Just imagine how amazing that would be and how many people will have the best time of their lives playing their favorite champions with a new different experience.
