The 1st Week of October every year, all champions should be free to play to celebrate Worlds

I would prefer something akin to a Compendium since, you know, that's actually relevant to the thing being celebrated instead of just saying, "let's celebrate!" "With what?" "Idk, let's do something nice but really has nothing to do with the event!" "Ok!"

Or maybe they could put all the Worlds skins on sale for the duration of the event. That would be fun.
