Sometimes late at night when the rooms are nowhere near full, I find that I am host in TDM games. In cases where the next map is Wasteland, I tend to exit and look for a new game and almost invariably, I get the exact same set of players and a new map, usually not Wasteland within a second. However, if I do this more than twice, I find myself not being able to join a room for short periods of time. At first I thought it was because the room randomly filled up or got merged, but then I noticed that the same players trickled into whatever room I was next placed in, which led me to the conclusion that I might have been blocked from rejoining that room for a short period of time because I kept leaving as host. Also, I find that when that happens, I am almost always not host for the next match, even with the exact same set of players.
Does this mean that I get marked as a bad host or is it just an 'intricacy' of the IW matchmaking algorithm?
EDIT: I'm playing on PC
