Hi there,
Thanks for posting some suggestions :)
One thing to also keep in mind with RoRs is not just their visually distinct aesthetics - which don't get me wrong, is a major part of what makes them cool - but also what kind of rules/abilities/traits in the game they could have which would make them stand out much more uniquely amongst their basic versions. The names and visuals are good to have, but suggestions for how they could/would work in actual battles or campaign is also key.
Thanks for continuing to share your passion for the Warhammer IP and Warhammer: Total War, keep it up :)
