Be the CEO for a Week!
You know how some companies do this? Well, okay, I don't think it makes sense for CEO but I could definitely make an argument for:
Be the Balance Team Project Manager for a month!
Maybe doing this and having the changes the new guy suggests implemented for a month following his reign in the pre-season.
I'm just thinking on this because I honestly believe I could have this game ontrack to be balanced within a week given full control of the decisions on champion kits buffs/nerfs and items.
