When i enter here i feel like when i was a child and use yogurt boxes with cotton to plant beans
apy:
Quality is hard to select, i usually use a basic value for regular units and move over or under it to have elite or militia units... maybe here 1 star can represent regular units (trained but not tested in combat or very few combat experience) 2 stars for elite units (maybe 3 in very special units) and 0 as standar in all militia/new units and combat values could be the diference between them.
Or you can add propaganda events, you can use political points to launch one that provide an increase in conscripts or at least reduce their cost in money/morale.
PD: ummm maybe i am wrong but the irish volunters suffer a lot in combat thanks to incompetent command and lack of combat value.
