First thing first:this mod is really awsome! Right now my most favourite stuff are minor factions, which flesh out world so much, and the whole Dogs of War faction - combination of famous units and heroes from Shadow of the Horned Rat and mercenaries is really flavourful, not to mention their area of recruitment system...
Now the question: why are Skaven Censer Bearers recruitable earlier and in larger quantities than Plague Monks in the campaign? Aren't they supposed to be specialised unit, while Plague Monks should be more common than them?
