I'm trying to put my finger on exactly what has changed, but in general I'm noticing the AI just not as good at war as it was say 6-8 months ago. I'm steam rolling over Immortal AIs now, when back in the day these wars used to be a serious endeavor for me. Again, I'm not exactly sure what has changed, I'm trying to suss it out as I play, but the just feels more timid, and maybe isn't making as many units. So not the most productive post, its all I got at the moment.
