If I have a huge army I shouldn't lose a "small fight" agaist a weak enemy. I should lose some units of course but not the whole battle, especially not if something like an RTS is simulated in the background. With a huge army I could overrun the enemy in the first minutes.....
I found that if the results are significantly in favor of one person the fight still usually ends with little casualties on the larger side. How about this as a compromise. If you outnumber the enemy by a significant amount (it would have to huge, say your force is 5x or 10x the amount of gold) then each unit counts as twice as strong in autoresolve. This would keep the current system but allow massively larger forces to steamroll. This is not ideal (I really like how the system works now. I find them very realistic although I haven't played the new beta that just came out today) but could possibly be a good compromise for players who feel that they can game the system with small armies.
