I wonder how many players would have been pissed at the devs for the freeze if they had known the War Islands might be coming back. It solves most qualms in this thread.
Doubtful.
Also, one has to wonder how creating more land is supposed to increase either activity or density.
Finally, I'd also add that while noble:region and nobles:realm ratios were mentioned, realms:continent ratios also need to be considered, because ultimately, other realms of the continent are the only ones a realm can declare war on.
