No, unfortunately all you have for that is to simply tell yourself each time to actually fight the battle, even if it would be boring just stomping an enemy. The fact is that if you want to guarantee an efficient win, 99% of the time you use auto-resolve. But then you'll miss a lot of the fun of the game, which is the big battles. I auto-resolve any fight that has one of my armies vs less than 12 enemy units, since at that point you have too much of an advantage to really be at risk.

Agree, exactly!
Make the upkeeps for troops more expensive so you dont have plenty troops to assure yourself so much everytime. Think about it.
Eehehe, agreed very much with the fireflux words, its very much loose all the fun of the game avoid the battles,is the game itself i think.
Is very cool use increasing difficulty mods and be forced to play battles, than see in the after turns that your actions in earlier battles made you strong enough to beat some challenges in the later game which you wouldnt.
