Factions Featured Game Mode!

So, As a participant and staff member for the wonderful Factions community, I've been thinking of how Riot could turn this style gameplay into a featured game mode.

Using the tech for Teambuilder, people would select the featured game mode, which would be 5v5 SR or 3v3 TT or 5v5 Dominion Faction builder. From there, rather than selecting a champion, People would select a specific Faction Like Demacia or Noxus or Piltover or the others, and then from there their champion pool would be limited to whatever champions that have ties to that faction. Since this is a unique featured game mode, I would say, for this specific gamemode all champs for each faction are usable, even if you don't own them. That means people could play any faction they want despite not necessarily owning the champs necessary. Then from there, you select lane and role, and then it matches you with other people playing your faction, after you've got the full team, you're then matched up against a random other faction that is not the same as your own.

FOR THIS GAME MODE THE FACTIONS ARE AS LISTED AND ALL CHAMPS THAT HAVE MULTIPLE FACTIONS ASSOCIATED WITH THEM WILL APPEAR ON EACH ROSTER!

DEMACIA IONIA NOXUS ZAUN PILTOVER BANDLE CITY SHURIMA VOID INDEPENDENT (All champs that do not belong to a faction) FRELJORD BILGEWATER(Optional, since there aren't any champions other than GP, Fizz, and MF that are directly loyal to Bilgewater And they can easily go under Independent)
