Man, I doubt I’ve autoresolved more than 10% of battles, really only doing so for battles that are extremely lopsided kill fests. Partly because I know that I can outperform the AI every single time. I just… can’t go into a battle with 2:1 odds, knowing I could take a major victory with minimal casualties, while the AI stands a decent chance of losing, and even in victory take losses that will take several turns, and lots of money, to recover from.
Which also ties in to the fact that the battles are some of my favorite parts, and that I have more hours in Total War than any series except Europa Universalis. So I guess I’m the outlier. The campaigns are mostly a battle generator for me.
