How does this mod affects AI training preferences regarding cavalry ?

I'm asking this because in my present Scotland campaign - my first with LtC 3.0- the AI almost never trained any cavalry. I've obliterated the english using nothing but massed highlander charges, since they never built anything but spearmen, with the occasional longbow or billmen. Absolutely no cav, except for generals. I had no use for my pikes...
Same with the french : I've fought 6-7 battles against full stacks of spearmen + a few missile units. I sent some spies across europe (HRE, Denmark, Venice, Hungary), and I've counted maybe 7-8 cav units among the 10-15 stacks inspected.
It's even weirder with the eastern factions, byzantines and turks, who were supposed to train a lot of cavalry : they have none of their native units : no skythikon, no byz cav, no vardariotai. They do, however, hire all cav mercenaries they can find. Why don't they train their own ?

Is this normal, or I screwed something up when installing the mod ?

I quite sure the AI trained more cavalry in vanilla...
