Playing as PG I'm constantly thinking of changing into something else since 90% of the players have gnp :P
Maybe because a lot of people that go PG/FS make one dimensional fighters and end up having trainers with 4.0 star stats whereas regular people who actually factor in MIXED MARTIAL Arts become more diverse while suffer from weaker trainers.
nae I think its mostly because GnP / SiO is very popular atm.
