It's kind of frustrating i got match into teams with regions or missions that i haven't unlock or I'm not going for. I understand all players will have different missions they wanted to play for and probably many players have progressed very far in the game. I hope the matchmaking can be further improved in future.
Allow us to filter:
1) The region or even missions (2 levels of matching if possible) that we wanted.
2) Difficulty
3) Playstyle of teammates we willing to team up with
In this way, perhaps we can meet more like-minded players and even form our own team.
