My two gildar:

• AI use of strategic spells - they need to use them, all of them. If mana is a problem, please consider (for higher difficulties) giving some mana bonuses to offset. The AI is gimped.
• Diplomacy AI - Refine the dogpile methodology and bring balance. There have been many posts on this with good ideas. Personally would prefer weaker factions band together to balance a stronger faction. As a player, if I'm top dog (or near top dog) I welcome the entire world declaring war on me to balance. If I'm the runt of the litter, prefer alliances or at least neutrality to balance the strength of the top factions. Have this scale with difficulty - if I choose the harder difficulties, I'm fine with everyone declaring war on me... I asked for it. But lower difficulties, make the AI more rational. Would love to see the entire diplomacy aspect of this game get tons of love.
• UI improvement to notify when AI uses strategic spells or negative city enchantments. As HF noted, right now the player can only see visually on the 3d strategic map. Furthermore, negative enchantments are not visible anywhere in the UI (last game I had 16x casts on a single city debuffing my defenders hit points... had no idea they were even there until I saw the debuff in city details. It doesn't tell me the name of the spell affecting the city). In addition, it affected my FP as when the 9 stack of defenders were in the city, my FP was way lower. When I moved them out of the city, they got all their HP's back and the FP rose substantially. This actually occurred in multiple cities.
• Consider reviewing the accuracy of FP and how it's calculated. Been here a long time and don't remember ever seeing details on how FP is calculated. Most often, the FP hasn't made much sense - someone looks scary on score but when push comes to shove, they get rolled. If you shared the current logic, the community might be of some help here with good ideas.
• A pony - oh, nevermind...

AI is bland.

Brad, you need to get WAY MORE FLAVOR TEXT into diplomacy.  The AI should constantly be peppering you with various insults (or buttering you up with new compliments).  I would love to have the AI, when losing a war, say to me something like "You think things are going well for you now?  Soon I will reload from a save and wipe you off the face of the earth!"

Clearly, you're sitting there thinking of insults, why not let the AI say them in the game?

Would you mind throwing us some development updates in the dev journals? This is point where the game gets really fun for me. I would love to read about it.

Haha, I agree and I am also thinking the same while playing.

Yeah - these are good spells too.  Disruptive, but not calamitous.  I remember in MoM the AI would spam Corruption and Raise Volcanoes on you all the freaking time and I got so fed up with it I found an editor that made those two spells cost a prohibitive amount of mana.
