New Game Mode- Faction War(name up for discussion)

5v5 Battle Faction vs Faction. Demacia vs Noxus. Noxus vs Ionia. Ionia vs The Void. Each Team Votes on what Faction they want to play and gets to choose champions from that faction. Tell me your ideas let me know what you think! Will there be new maps? Maybe one in the Void or Ionia? Or maybe the castle in Demacia? Maybe just new map skin setups for each map depending on what faction is attacking or defending? A ruined Crystal Scar? A burnt Summoner's Rift? Give me your ideas!!
