D'Hara seems to have reasonable activity.
And your point is? They lost little except a couple of regions and a bunch of gold (and, well, peasant soldiers) when the west island was closed. I don't know how many players they gained, I know that several characters did join them, but Morek hasn't really received a boost and the nations forced to migrate are or have lost far too many players (if they still exist) for the most part. Many of those players quit the game entirely, which is exactly what BM doesn't need.
I don't even really know whom half the people in Barca are anymore.
