why only a choice of 2 maps?
Then only the most popular maps will be played. Remember Nuketown and Hijack every other match in BOII. It'd be even worse with more choices because odds are higher for each map to appear.
Personally I like to see no choices. You either play the map or you leave. And all maps must cycle through before one is repeated in a lobby.
Sorry, I know you want more choices.
wish there was the option of a rematch, same team members, when the game ends in a tie.
I like this as well. Nothing much more frustrating than not being able to play a rematch against a team/player that just got the best of me.
Unfortunately, most players don't like competition and avoid challenges. If they win against good players, they leave the lobby because they know they'll likely lose a rematch. If they lose or are losing, they probably already quit mid game.
