Guys, it's a bit hard to discuss the meaning of some numbers in xml if we don't know how they're used. For all we know the numbers might get subtracted from 10 and so they're all backwards, or they get put into some formula which makes these values by themselves of not much consequence.
El Caballerion, you ask why Genghis is only a 3? Maybe it's because there are several factors in play and an aggressive or expansionist leader doesn't necessarily need to be a deceptive one (i.e. I don't know). Purely from my experience with civ games and nothing from real history education, I'd expect Catherine to be highest or equal highest on the list.
Then again, maybe Optional knows more about the numbers than I'm giving credit.
