I specifically don't mop up, and I play with Alex-EB. When the battle's over, it's over. I was finding it unfair that when I lose a battle, I never get wiped out while the enemy always does against me, just because I let the battle go on longer than it should.

I've been liking this. It adds an extra challenge, and I end up having to find ways to kills the commander before the whole army routs (sometimes the FM gets away!) - and I end up trying to kill as many of the enemies while the battle's still going on... Sometimes the enemy host will live to fight another day, sometimes they disperse. It's more exciting to me this way, and it feels more realistic.
