I have tried various Ffh modmods and I think this is by far the one with the best AI and balance.
I often have trouble playing well in prince if i'm unlucky / have a bad starting position.
The AI usually seem to use world spells appropriately, assemble balanced marching armies/SOD's and seems generally competent.
Content and flavour wise I think base Ffh has enough, and adding or changing game mechanics, such in in other modmods, allways in one way or another upset the civilization's balance, and either overpower or nerf some factions/units etc too much, and leaving the AI unable to use the new features properly.
Having played quite a lot of games to at least mid-late, I have however noticed some issues with how the AI handles some features:
The Balseraph never seem to upgrade their freaks to suitable units (light and mobility promotions goes scout units etc.) even thogh the cost of upgrading these to 2nd tier units (archers/swordsmen/ hunters) is only 5 gold per unit, leaving them with only a huge army of freaks.
Also, getting Loki early and disrupting early rival settlements is a core early game tactic that the AI don't seem to utilize well.
I don't know how the AI works on assesing the chance of defeating an enemy army/ stack and the cost of doing so. It too often throw masses of mediocre attackers against city walls, or dug in archers on a hill, without siege equipment or other means, to cause colatteral damage prior.
Hmm.. can't think of much more now (that's how well the mod works
Yeah, powerhouse civs seem to declare wars left and right before even finishing off/vassal civs they are in a campaign against.
Also an attacking civ staying with his army in my territory plundering (because i have adequate defences) while i sneak in a small elite force into his territory taking or razing his cities, not reacting fast enough to it.
Not an AI issue but i never liked the Idea that Basium will follow Ashen Veil /Overlords civs. Imo the Mercurian Gate building should be restricted to neutral/good and or Order/ Empyrean civs.
I think Tsunami and Ring of Flames are too powerful as they are. Maybe nerf them to max 20% damage to a stack?
Fianlly; I would nerf the Calabim Governour's Manor building, it's to powerful imho.
Unfortunately i don't have any programming skills so this is the only way i can help.
Looking foward to the next release!
