Although this mod is absolutely amazing and I vastly prefer this over the vanilla there are a few tweaks I think should be made and any other suggestions can be added with a comment, so here are my suggestions:

- Adding very low tier units (Like peasant mobs, goblins and skavenslaves) to Tier 2 buildings would add a nice little extra defence to less developed regions. No real lore reason for it but I think it would be nice to have

- Changing the Undercity discovering building so that the infantry have the fanatics instead of the archers. Again not really any lore reason it's just that it makes more sense for the fanatics to be on the unit rushing into melee

- Major settlement walls are kind of lacking in purpose and have some weak units added to max level when they have stronger variants, for example Clanrat Spears could be replaced with Stormvermin Halberds. Once again no lore reason but instead a balance reason, where the walls aren't that worth it if some of the units they give are only mediocre

That's all that I can think of for now but if I find a few other instances where either a unit could be added or a loreful unit seems to be missing I'll add a comment
