I love RPs, but I can do much more RPwise in a realm like Sirion than in Luria... Sirion at least is always involved in wars, even being always safe and even being until a short time ago a Behemoth... or a white elephant in the corner.
What will you RP in Luria? Your character walking through the beautiful streets of all your seaside towns? At least incite a civil war between your duchies (in Luria they are still considered small kingdoms within the empire?). Or try Madina... I'm in Bol just holding courts and killing monster. In fact, a good RP isn't always in a Roleplay Message, but in the trash talk before and after a battle, the rivalry and hatred that only a war can bring.
