I play on the first trial day of SE Asia server. It is better than I expected.

Queue time in 3 matches continuesly:
(1) ~10 mins
(2) 7 mins
(3) 4 mins

First and second matches were full players 5x5 in 2x3 rounds. The third match was weird. I sent to a match called "Lobby" with 1vs1 in 3x3 rounds. More players came to the match after 1x3 rounds, but 3vs1 as me the sole team. After 2x3 rounds, the match reset with more players. It turned out, that match called "Unrated" which I queued for. So, not sure how long it takes to get me the real third unrated match.

I cannot say anything about game mode as I have to learn more. But the training mode seems to be unfinished, lack of basics.

There was Aus server's player in one of my match. He said that SE Asia is much better than Aus for active players.
Hopefully, they keep SE Asia server and the game developments.
