Capture the flag seems to matchmake the best. I have yet to get into a deathmatch game. Team deathmatch seems to happen but then is always one sided - ie 3 vs 1 when 4 were waiting.
Some stuff definitely wrong atm but can't think what else to say that's helpful. Anyone else getting a similar experience?
I agree about the teams being off balance, and the games starting with insufficient players. I however, can't find a CTF games, and can only find TDM.
