Having just quick play, btb, and competitive is really not that much.
Would be cool if we could have like a lone wolf playlist, action sack, infection, slayer 24/7, snipers, big team battle heavy, 2v2, swat, oddball, maybe some community favorite maps as playlists too like a recharge 24/7.
I’m sure it will come with time. They probably just want people to get adjusted with the safest gametypes. Will surely help bring in newer players that way.
