I don't think his problem is "NPCs don't use the exact same character creation rules as PCs" so much as "NPC wizards can magically fly with no duration cap, teleport anywhere on the plane as a standard action, and summon Pit Fiends who have full stats and don't eat into their actions" - you know, the standard "NPCs are all cooler than the poor benighted PCs who have to play by the rules" stuff.
So while a Jorasco healer doesn't have to be written up as a PC of any level at all, the Mark of Healing is written up as a slight boost to healing - not a godpower that gives you unlimited superhealing. So he'd prefer the NPCs to be described as using more like Dragonmark-boosted Healing Words than projecting an image of a great pearl dragon from their Dragonmark into the air that fully heals all allies, because the latter is not what Dragonmarks do.
Do any of these examples actually exist somewhere that I'm not aware of, or are you just practicing hyperbole (or blowing things out of proportion)?
