Can't speak for the other tribes, but for fellow Hotgo players there's quite the justification built in since our entire tribe was massacred by a savage tribe. Seems like it'd be hard to just integrate into a new tribe unless it's one of the very specific ones that cater to bringing in loners, so it stands to reason that setting out on your own to survive would make sense. Finding themselves in Eorzea is certainly in the realm of possibilities.
