I haven't played as Eriu with the latest version of CBM but one thing I noticed from an MP game with CBM 1.92 Eriu is that they get the Bean Sidhe as recruit-anywhere instead of capital-only, AND the Bean Sidhe gets a 15% forge bonus. That makes the nation kind of Ulm-y since your primary research mage and support caster also has a forge bonus. Plus, glamour, thugs and air/nature magic galore. Ever since that discovery I've been pretty interested in testing them out... just some food for thought.

EDIT: Marignon is fun, potent, and full of burnination.
