adding a tag / hide'n'seek in the summoners rift

I was thinking riot could possibly make a permanent mode in wich you play as a hider or a seeker. In this game mode, everyone picks a champion (melee) that can either hide or seek easily. As a seeker you play in the blue team, and as a hider you are on the red team. Once you have found someone (you have to tag him, auto-attack) he comes in the blue team and becomes a seeker. Once everyone is found (or the 5 minute mark has been achieved) , another game starts, and the first player found in the last game is the starting seeker. this is a 3 round game and the winner is the one that got found the least amount of times.

Hope you guys are going to be in favor of this gamemode! I would love to see it come to life! Thanks, MsrUnrealice
