Just now, I tried to get into a game but the matchmaking algorithm kept dumping me into the same Firefight match, which was already 2-1 and into the final round. Maybe it's just me, but it's really annoying to wait in queue only to get put into a match that's, for all intents and purposes, over.
It would be nice to see one of two things happen to stop this:
Change the matchmaking algorithm.
Give players the option to be placed only into matches that are waiting to begin.
