FFA slayer join mid game

Unreal this was added to FFA playlist. I don’t want to play FFA if i start the game down by 5. On the flip side i don’t want other players to join mid game just to be frustrated and quit. Seems like this is obvious oversight. It creates a cascade effect making it harder to find FFA games bc one ruined lobby keeps pulling players in. Happened 2/10 games today. I Have a hard enough time in FFA as is.
