The Summoner Games

Me and a couple friends were thinking. What if Riot introduced a Summoner competition where you sided with a certain faction to represent during games. During the game the faction would give you a flat bonus based on what they represent and a shifting bonus based on your score. At the end of these games the top three players (taken from both teams) would earn points for their factions. It got us really excited and we wanted to hear what others think of the idea.
