I played some more and I kinda miss an auto-resolve feature. The battles take a really long time once thousands of units start fighting (which is kinda easy to do playing Wild). Letting the monsters run gives full xp, but doesn't trigger demonology even though there's xp to sacrifice (and yeah fighting would risk losing units even if infirmary +tent brings them back even though losses are unlikely if you have a strong army.)
Even if an auto-resolve ruled somewhat unfavorably in my disfavor I'd still love to have the option to do it if I'm attacking a fort where there's no way I'd lose and to trigger victory skills like diplomacy or demonology when running wouldn't do that. Sure I could fight, but I'd lose a lot of real-world time doing that so I don't really want to.
