Please dont remove content , especially for pvp.
Just add it to a rotation and you que for all of the game types at once and it semi randomly assigns you to a game.
If not enough players it plays a mode appropriate for the amount qued and just have it check how many people are in a que like every x min to give people time to clump.
Ahh yes like others suggested.
Even number = team games
Odd number = FFA
Large odd number = team games with a juggernaut on it’s own team. Give it all the dev slayer buffs and whichever team kills it gets extra points for the game they are trying to play.
