I tend to agree that the best thing would have been to sink the eastern half and leave the western half.
However, what's done is done and we have to live with it. A major problem with Dwilight at the moment is that Morek is severely depopulated and Luria Nova is vastly overpopulated. How you fix it I don't know but I do think that a fundamental problem with Dwilight is its geography. Things could be improved if Morek was replaced by multiple, smaller realms to bring conflict to the area but there's really no IC reason for anyone to do that.
