One thing I noticed. You only play in one realm and one world. Why not try elsewhere for a fuller experience? This is one reason for having multiple characters, so your game enjoyment isn't all in one realm/world basket and its success/failure. As mentioned, there are wars on the East Island. There were wars awhile ago on the Colonies, but I have not heard news from the Colonies lately. On Beluaterra, Nothoi/Dominorum vs Nothoi has an ongoing war in the midst of a daimon Invasion. War Island...eventually.
-.-
I would suggest to just go ahead with the split and continue killing rogues as you engage in inter-realm politicking. You may be the middle of the island, but that is irrelevant to rogues having mostly surrounded you. Seeing orders and clicking mechanic buttons in response doesn't take away from the 12 hours in-between turns that can be used to roleplay and describe what your character(s) are going through fighting against the monster frontier.
I agree that The Freeze was a mistake, and I wish we had done the suggested overall ramping of monsters, rather than targeting an area. And sinking Atamara then, instead of all The Freeze business. But I cannot change the past, only learn from it. This recent more gradual monster increase has been one lesson learned from the too-quick swarm across the West in The Freeze event. The spawn rate is based on the overall density of the island, not specific realms, which means all rogue borderlands feel pressure when island density is lower. As mentioned by another poster, taking regions back from rogue will lower the density, if equivalent regions are not lost elsewhere on the map or new characters created/immigrated onto the island.
The rogue's purpose is not specifically to kill realms, just to spawn and conquer regions in accordance with island-wide noble density of held regions. The daimons are not gone, but the fact their last region was taken means the daimons are no longer distracting the monsters as much.
Once you make room for your head by removing the frames, you could probably stick your head safely into a hive without getting stung. Though most of the bees will have been removed, by removing the frames. And you'll look rather idiotic. Bees are rather peaceful creatures, you know.
