I've left the game, but I'd just like to point something out regarding "things were done in-character and are okay".
There were many, many issues with Thulsoma, one of which was that-one-game-feature-that-allowed-Thulsoma-to-raise-a-huge-army-despite-being-a-one-region-realm (I forgot, long time ago now). That mechanic was changed because, while it was a valid game mechanic at that time, it was deemed to have been used in a manner that was detrimental to the game.
Precedent, therefore, exists, for changing mechanics when it's shown that they are too troublesome. Of course, Thulsoma wasn't deleted and Morek still had to war with it for a few weeks, but at least the mechanics were changed for the betterment of the game. In the same manner, I do hope the dev team looks into the 'game-able' mechanics that came into play here, so that in the future, Battlemaster players would not be unduly punished by a handful of people who are good at powergaming (especially in an SMA island).
