How do you be pro in combat arms

In my opinion, there are no such things as "Being a Professional" in Combat Arms. But there are leagues for competitive gaming against other descent players.

Where you can start off with is to go to, cyber-sports.net (Cyber-Sports Network) which is the new competitive league for Combat Arms. [It used to be WOGL (World Online Gaming League) until it became untrustworthy.

In-Conclusion, play against competitive people, or, more experienced people to become a so called "Professional" player in Combat Arms.
