I am against respawning,too. Its just annoying when you go into an area you cleared earlier and all the people thanked you for that and celebrated you as a hero nut in reality you wait just five minutes and the enemys are back.
If it fits into the story, like when i killed a big fat troll and some time later the village has now a big problem with many little orcs instead a small problem with one troll, it would enjoyable but mostly its just annoying killing enemys you killed before and then getting only +1 EP.
