RPGuild is not an alliance of some sort with a single core philosophy or particularly strong sense unity - we're just a melting pot full of different people with different outlooks, who all just happen to enjoy RP fighting and have settled down on the Guild at some point.
So yeah, dig deep enough and you'll probably find what you're looking for. Or maybe something you never knew you liked and needed.
Regardless, isolationism is only going to further deteriorate the RP fighting community as a whole. If we want new blood and a bigger, better, more exciting future for the craft, we gotta stick together. Nobody's going to interested in a form of roleplay that only remains living within a handful of self-containted cliques composed of two and a half people each; nor is such an existance going to be fun for the participants themselves.
