I would like to mention that skills aren't the only thing that matter, if you have a really bad personality no matter how good you perceive yourself to be in JJ2, you'll have trouble joining clans. Take Genex for example, he's not "super-duper good at JJ2" but like he said, "the line behind him is long." Why didn't he get into GpW even if he's above average? Simple, he failed because one of the criteria is personality.
