Rout Limiting

[Havoc]

I know this subject has been debated to death. However, I was just wondering if anybody out there could hazard a guess as to what percentage of players use this optional rule. Also, does anybody have enough experience with it both on and off? It seems this optional rule can stir huge emotions in players. Even with it "on" I've seen large portions of armies "run for the hills!"

I supposed that folks don't want to lose a battle simply because half their army up and runs. Realistic, but not very fun to play if your side has the crappy morale, though this tends to make a battle bloodier than in history due to units staying and fighting longer. I'm ambivalent to its use; played both ways.
