The "Best" player, is a person who can read a fight the best. Know when to stay high, know when turn fight, know when to stall fight, know when to hold em, know when to fold em.
But the first person that comes to mind who has the BEST ability to read a fight is Anarchy and Bruvv. They always seem to make the right move or know what do when they're outnumbered.
Vudu15 is a beast in the KI84. He can easily handle a 3v1.
But yea, the best pilots, are those who can read and analyze a fight very quickly and take advantage of a persons weakness.
