The pressing problem with intra-realm conflict is that, in the end, you need to be part of some realm. If you have some group that acts for its own interests that are separate from the realm, then either your group ends up gaining control over the realm, or you fail. More often for many more groups than not, failure is the only result.
What then? That leads to migration to another realm, to attempt the same thing. It's happened more times than i can remember. We all know this to be true. When a group loses in their bid to become dominant, they either disband or try again in another realm, or, if their original realm doesn't banish them all for their insolence, try again in the same realm a while later.
All the while this weakens not only the realm as a whole, but in fact weakens the very structure that allows such groups to function in the first place. Unless the factions' goals are complete anarchy, which would overtly go against what BM is supposed to be, then the factions really do need a stable realm structure, or they would fall against some moderately powerful but much more united realm.
I think there are some leaders of these factions who are veterans to this game, but have grown myopic in their goals, failing to realize that having a more unified realm will allow them to actually have something to attempt to influence. Most times being a manipulative chessmaster results in you manipulating some smoldering ruins. If that's your cup of tea, then all the more power to you. But who ever really thinks about the effects on people who came into this game expecting to, you know...battle against other forces?
