So after playing for a few hours i have quickly noticed a few different things.

1 The cost to maintain a army large enough to fight against the other factions armies costs a load. I have about 420 troops (Mostly mid range troops) and it costs almost 5.5k to uphold.

My idea to fix it is to either raise the amount that enterprises in cities give (Allowing you to make more money) or just lower the cost/wages troops have (I have leadership 6 btw)

2 Increase the amount of units allowed on the battlefield or lower the average size of armies (this could also help with 1) Because having a 450v420 battle and only 150 (75 troops each) fighting at once takes forever and just draws battles out.

If i think of anything else or anyone has to add on then please do
