Well, after a few days of experience, I have to say two things:
1) the general attitude of veterans is quite funny (as in, borderline/disturbed). But at least they play well. There are exceptions though, like cilverBUG, and others, who are very polite.
2) too many people who set up large maps in 1vs1 to have the time to rush titan.
So, the game is nice, the beta multiplayer suffers.
