Social games being set up so differently from ranked games make them not useful as warmup matches, where everyone is going to be sweating with comms, br starts, consistent weapon spawns, etc. We need a social playlist that emulates the ranked playlist.
In fact, I think the current ranked playlist would make an EXCELLENT warmup playlist, and then the REAL ranked playlists could be split by gametype, and allow us to queue for whatever games we want to play.
