Yeah, I love fleeing enemies. Especially fleeing enemies that throw a Grease bottle in a chokepoint and then go call their friends, get healed and come back (bonus points if they slip on their own Grease).
Am I masochistic? Maybe. But it just feels wrong that no one begs for mercy unless it's scripted, no one tries to flee (except that very intelligent scared boar in Act 1, RIP Scared Boar) or otherwise stay alive when they realize the murdermachine that is the Avatar and their party of misfits just cannot be stopped.
Humour us masochists on the highest difficulty level?
