also what about leveling up skills? i wouldn't want less stuff to kill and loot for food or crafting resources.

I think he's talking about just having mobs that are several biomes lower than the player level not blindly attacking in a pathetic suicide charge.

When you're toting Plains or Mistlands level gear and skills, having Graydwarves mindlessly fixate on you is kind of like the poor shmuck Army guys with rifles shooting at Godzilla. It's a pointless, doomed effort for the Army guys, and nothing more than a minor annoyance to Godzilla that wastes his time.
