As far as you know, AI behavior on the campaign map is controlled by the descr_strat.txt file and by the line which starts with faction factionname. (may be by smth else as well) For example:
faction seleucid, bureaucrat caesar
where the first word (here bureaucrat) controls Development and Strategy, while the second one (here Caesar) - controls recruitment preferences of the AI
Genghis – scirmish and light cavalry
Caesar – heavy infantry, light cavalry, artillery
Napoleon – light and heavy infantry, light cavalry
Mao – mass light infantry recruitment
Stalin – mass heavy infantry recruitment
Smith – no preferencies
Henry – heavy and light cavalry, missile infantry
This is well known information, if you want, you can look for it, unfortunately I don't remember exactly about Craftsman, Sailor and so on,
That is theory.
And now lets speak about the practice. Who has tried to edit this lines to get different AI behavior, with other factions being *colorname* fever?
After editing some of the characteristics of several factions, I picked up Casse and wait and see what was going on. (on Alex exe)
Yes, Ptolies are not Yellow Fever anymore after I made them Fortified Mao (sit still and develop, use light infantry).

And now I will need your help. Backup your descr_strat.txt, and experiment with this file. Lets make Pahlava, Hayasdan, Pontos and Casse new steamrolls.
