Hmmm the reason for this is the inability to raise the amount of xp a trained unit gets opposed to sov/champs, unless someone solved this and I missed it.
On a side note, is there a way to set a trained unit trait to only allow one or the other to be used so I can set up a rudimentary system for weight classes. In other words minor classes for trained units not as good as henchmen but like a subclass. Mages already exist, but I want to make it that the mage traits for magic have a -15 weight on them. Scout has no weight bonuses, Medium unit has +20 Weight, and heavy unit has +40 weight. I know we can't use unit tags yet so I am still trying to make the AI use weights by making predefined sub-classes with specific weights then make predefined units for the AI to use. I can get this to work with armor but damned if I can figure out how to get weapons to work. Without unitstat tags to force a specific type of weapon to a sub class this is probably not going to work.
