Now I confirm you haven`t tried these MODS I mentioned. I guess you just love bumper cars. Childhood nostalgia?
I will concede though, beneath the relentless stubbornness you have some sort of a point. In IV AI made many stupid things as well (much less with the AI mods, but still), combat wise specially. I guess It wasn`t every time, but somehow it managed to pose a real and nice threat (given you were playing the appropiate level for you), all of which in the last two games it fails to do.
Mnmnmn... maybe it just needs even more buffs and bonuses as it was suggested. The fact remains, why wasn`t it done already?? Can it be done at all without making combat even more ridiculous and lame???
That's really the question here. I mean stacks have been done and done to death and the most that could be done was to just give the AI larger stacks and it was still pretty stupid. I mean, sure, an AI with a stack 10 times larger than yours could be dangerous and scary if you somehow couldn't collateral it to something nonfunctional, and also couldn't control it some other way. It's rather farfetched given how just changing your government makes the Civ IV AI your bestest friend.
So why hasn't the Deity AI been given literally +100 Strength bonus? I get the feeling that players might find that kind of offensive.
Let's presume that the AI can't do brilliant tactical hex combat. It's a script, not true AI, so it's kind of hard to make it perform well given that it also has to be fast (can't make it think very long). If you want it to be a threat, just boost the Strength the way AI stacks just have more numbers on their side. By how much Strength is fair for which difficulty levels?
I don't think we can know that until other problems are fixed. Right now, I CAN (and do) wage war without taking cities. I do it for the district pillage and if I'm Gorgo, I do it for the culture. In fact, I DO wage war against one-city Civs sometimes just to farm it for unit experience. Not sure you'd have made sense of that, but I do it and it works for me. It's hard to make something that looks human, so even in Civ 4 I give them the benefit of the doubt and squint my eyes a little.
I know I rag a lot on Civ 4 AI here, but I had fun with it and it's okay enough. Outside of unfavorable comparisons with other games of the same lineage, I'm pretty okay with it. All of the Civ AIs are dumb compared to GalCiv AI, for instance, but GalCiv is built around the AI, not the other way around.
