Big Changes

- Difficulties rebalanced, and AI builds A LOT more on the higher ones:

Hard : AI (excluding player vassals) has 30% cheaper build cost and no other bonuses.
Very Hard : AI (excluding player vassals) has 50% cheaper build cost, and no other bonuses.
Easy : Domain Tax +25% for player and no other bonuses.
Very Easy : Domain Tax +50% for player and no other bonuses.

As I mentioned previously, the building logic was already fixed in the mod, the AI was just missing the money.

- MAA regiment size limit changes :

Every MAA innovation now gives +5 to maximum size (from +3 / +4 / +5, with higher eras giving more).

Cultures with all innovations researched will now be able to field up to size 20 regiments of MAA (up from size 17).

- Burghers (city vassals) will have their tax obligations slightly increase depending on crown authority.

Experimental changes to Warfare AI :

- While attacking and winning, it should push and press forward more, otherwise it should withdraw and regroup if it already has the wargoal, trying to hold onto it, but evading engagements otherwise.

- While defending and winning, it should try to grasp the wargoal and seek decisive battles with the enemy, and if said enemy runs away, try to siege and prioritize the capital while doing so. Otherwise, it should try to hold onto the wargoal, unless hopeless, then retreat, regroup and look for opportunities to retake the wargoal, evading engagements unless the capital is about to fall.

- AI now won't care whatsoever about secondary participant's land, only their armies.

Wars should be shorter overall, big battles and sieges more frequent, and the AI should actually go for what the wargoal says its going for, rather than chase the allies of the enemy war leader.
