So I'm a decent way into my Rome campaign (Year 127 BC) (N/N) and I'm starting to notice major problems (imho) on how the economy and income/game mechanics work in this mod.

1) Income from trade agreements is way too high: players inadvertently gets accustomed to this income to pay for building/army upkeep only to realize breaking this trade agreement to expand your empire will cost you (in my experience) up to 20,000 gold a turn; creating or exacerbating deficits.
2) AI does not develop resources: negates one of the benefits of trade with AI factions - giving you access to needed resources. This forces the player to expand their empire to acquire these resources. Leads to the first problem listed prior.
3) Provincial building upkeep costs too high: little point in building past the second or third building tier. Even then, upkeeps are very high.
4) Provincial corruption: it is very high. For example in Italia for me it's 78%.
5) Overall provincial income: negative. building upkeeps and corruption result in the majority of your provinces losing money hand-over-fist.
6) Legion upkeep too high: 10,000 gold/turn for one full stack Marion legion?

Other concern(s):

7) AI does not attack your settlements even if they have numerical superiority. In fact, they don't really attack your field armies at all, unless they have a ~2:1 advantage. This is easy to exploit and results in you taking settlement after settlement without having to fight their armies in the field.
8) Every town/city battle is a siege battle. Initially early game this was cool, but now it's getting a little tedious.
9) Auto-resolve battle is messed up, results in staggeringly high casualties for your legions.
10) When do we go from a republic to an empire so I can get Augustian and Imperial legionaries?

In summary: I love the mod, great work guys. I have an empire that essentially resembles the starting position of the WRE in vanilla, have 1.6 million in the bank, but with a deficit of 12-40k a turn. To expand further I'll need more armies (= more upkeep) to gain more territory (= plus building upkeep and corruption) which at this rate will bankrupt me. I don't know what to do. Any assistance will be helpful.
