Creating a New Rotating Game Mode: Faction Wars

Considering that Riot Games is making strides towards creating a much more compelling, vast, and story-driven universe as of recent (seen through the interactive world map, release or short stories and comics with Marvel, and well thought-out cinematic shorts), I think it would be a great addition to the game to have a rotating game mode that pinned two factions together in a 5v5 brawl.

This is open to interpretation and I, by no means, have a perfect vision or final say in what this might look like but here is what I think it could be like:

The premise is that Factions are invited to some grand tournament to settle which nation is superior. The map is either exactly Summoner's Rift or it's a slightly altered one (3 lanes + jungle but formatted less like a square and more like a circle) that resembles a sort of Colosseum. In the Champion Select lobby, both teams' players will vote for which Faction they wish to play (Demacia, Noxus, Ionia, Bligewater, Zaun, etc) and it is chosen via majority rule. If both teams pick the same Faction, a coin toss determines which teams gets it and the other team will have to choose another Faction. Once chosen, it's a blind pick of all the Champions that belong to that Champion. Assuming everyone follows the 5v5 Standard, you can expect a Demacia v. Noxus game to look like: Garen v. Darius (Top), Xin Zhao v. Talon (Jungle), Lux v. Katarina (Mid), Vayne/Sona v. Draven/Morgana (Bot). Once the game starts, the bases will be either completely overhauled to match the Faction or may just have small tidbits like flags and/or different patterns on the towers/tiles to represent the faction. For example, the Bilgewater base might be a complete overhaul to resemble a port of Bilgewater, or may just have Bilgewater flags hung up around the base and have Serpentine structures as towers, whereas Zaun's base might look more mechanical and run-down. I'm thinking the Minions could also be changed for each team to better match the Faction's clothing/weapons. The game would run as a normal Summoner's Rift 5v5 but perhaps there can be more impactful 'Lore Missions' throughout the game. Yknow how if an Ashe and Sejuani are facing each other in a normal 5v5 game there sometimes pops a mini-quest in the corner of the screen? Maybe we can have more of those but have real repercussions such as increased gold for the entire team or extra vision granted or some wacky RNG like the Catapult from URF or the Viktor Ult-Towers from The Teemoing. Also, for the sake of canon (non skin line) story, all the champions would have to be played in their Default skin.

This would obviously be A LOT of work and there would need to be more champions to fill out the Factions with less Champions pools like Mount Targon, Piltover, Bandle City, The Shadow Isles... and it could also be a cool idea for the VS event in 2020 or even 2021.

If you want to add anything or bring up other unique concerns/thoughts about this, let me know! Hopefully the Devs see this. I know it's a big project but I think it would be SO COOL. Seeing that Ionia vs Sion fight in the Awaken MV makes me want this to happen SO BAD!
