I don't know ... I guess if I was playing and I thought that there were at least two alliances that didn't include me, this would be a good time to try to get them to get squishy with one another. Of course, they, on the other hand, might decide to avoid that kind of trap and gang up on smaller fish. Unless, of course, the smaller fish have bigger friends, or one of the alliances decides to backstab the other to get a numerical edge.
All, of course, assuming anyone even knows what alliance they are in. If any.
It makes my head hurt.
