What he said was not overly disparaging of Luai, but it certainly comes from a position of arrogance.
Basically put's the ball in Luai's court, you think you're good enough? ok go see how good you are, see if you can handle the pressure. See if you're any better than, Capewell, Kikau, Cricthon, Api...
