You've reached much the same conclusion I have, it seems. Even for some of us who technically have worlds to return to, we may not wish to, and in that case, one world is as good as the next. If we can be of some good here, all the better.

The question that follows, though, is how to organize those who will fight, who can fight, before they're needed again. From what I see, even the attempts at organization are disorganized.
