Please reduce the required number of players to start a match.

I wanted to play Domination to complete a challenge, but the screen displayed “The game cannot start until 14 out of 16 players have joined.”
The 12 players who were already there had to wait over 5 minutes. When we finally reached 14 players, I thought the match was about to start.
But after the “Match starting” message showed up, we still had to wait several more minutes, and eventually most players just gave up and left.

Why exactly is it 14 players minimum, and not possible to start with 12? Since this is not a highly competitive game, it should be acceptable to play 6v6 or 5v5 until more players join.
Alternatively, like in other games, you could let us play a warm-up deathmatch before the match begins, or if there simply aren’t enough players, fill the empty spots with AI—anything to just let us play.
