New gamemode idea

I am really tierd of playing same rotating gamemodes in league of legends so i thaught everybody like silly gamemodes and events, so what if riot creates new gamemode named "Scuttler's vengeance". Name is meaningless but game mode will be like this: Scuttler the most unsinn creature of of rift will find way to grow up and get strongest creature (like rift herald from star guardian event) and decides to destroy "summoners Rift" or just kill all the players once and finally.

1. it will be impossible to kill scuttler
2. gamemode will be impossible to win or there will be 2 teams and team who survive longer wins (like noxus siege).

My idea is not finished yet but if you like it and want to see that gamemode in league, lets talk about it
