Gamemode: Fight for the First Lands

In Awaken, we see that the second Noxian invasion of Ionia has begun. So then what if we just want to help defend Ionia? Or fight Noxus? It would be a large number of players on both sides: Ionia and Noxus. The players would choose which faction they want to fight for before entering their first game, and the champions are randomly assigned. Blank map, with barriers on both sides that would stop anyone from running, that also slowly close in. Then it's a fight to the death, and anyone who exits the barrier takes small amounts of damage at a time. At the end of a certain time, the factions with more wins would win the invasion. It'd be nice to have the playerbase control the lore.
