basically, what i'm saying is that the patch makes the cultural win too hard to accomplish. if i play with a small empire, i won't attack enough so that i can have a decent amount of culture from killing (i think it's an advantage in the honor branch, which btw makes the Aztecs even less appealing) and if i play with a big empire, i can't rely on the broadcast towers which are now useless. in any case, cultural victories are almost out of reach lol.
Igoring the fact that Honor only gives culture from barbarians, the culture you get from combat has always been peanuts after the Classical era. The Aztecs' strength actually lies in playing it small and tall and the easiest victory condition to pursue with them has always been scientific. Unless you're constantly at war with everyone, the culture from kills just allows you to neglect your culture buildings while you establish your first policy tree.
How difficult a victory condition is depends a lot on your playstyle.
