Does the AI even use mercenaries? I generally assume not, since, you know, they're the AI. They don't use a lot of stuff. I'm wondering if these neat NI's for mercenaries are relevant except for people who play the relatively weak nations that get them? Which is not to say they're pointless to implement, but it'd be nice to know next time I look for a vassal whether or not it's going to live up to its potential.
So, to what extent does the AI use mercs?
To a significant extent.
