They should let you choose which map you want to play your mode in..instead of the timed switching, in my opinion.
Noticed lately that there are a lot more disconnects...especially when in trios, and the 3rd squad member selects a hero etc, and in game its just two people...have to double check every time i selected trios and not duos.
Also, had an experience where i shot a person twice with the Kraber and they still didnt get knocked down..actually had that happen to me twice in a game, one was a wraith and the other was a Caustic.
