May I humbly make the following suggestions :
- Primary weapon should really be much closer to the units' types. You could have different types of cavalry lances for heavy cav, types of pikes for pikemen, types of bow for bowmen (also depending on the culture between composite/short/longbow etc), infantry could have acces to more like either maces, sword, axes etc, while some unit traditionnaly used a very specific weapon, in that sub weapon types could help (even just fiddling with the quality, material etc to make the weapon type)
- the levy size debuff is pretty harsh imo, as it impacts the global levy pool. You get to -100% very fast
- I feel like it should rather increase either the unit's or you MAAs maintenance rather than cost a flat amount of tax, cos as of now equipping poor to middle quality units is much less worth it than equipping strong units
In any case, this is really just to better you mod which is already great !! thanks
