I would absolutely love to see small scale NMs in the game.

I'd like to see a good deal of them at a difficulty relative to the placeholders, say you have a party skilling up on moles in bloodshore, the mole NM may pop and would be a TOUGH fight in relation to the normal moles but would not be impossible for the party that are skilling up on normal moles. There'd be great incentive for normal SP parties over guildleves if you knew an NM would spawn with good drops
