Same opponent(s)/teammate is sometimes quite frequent if you don't change between axis/allies between matches. There just doesen't seem to be enough players around. Other thing about automatching is that lately I have constantly been matched with people of higher ELO than myself. This can also be blamed on low number of players though.
Also 2v2 mappool seems to be a lot smaller to the automatcher than it is in reality. I don't think there are so many vetoes available that the most frequent maps should be Moscow Outskirts, Trois Ponts and Road to Kharkov. I can literally count occasions where I can get Moscow or Kharkov 3 times in a row!
