I can understand the desire or want to have more / different NPC statblocks, and there's nothing wrong with that desire. But I personally also think there's no reason why any (general) DM shouldn't be able to or want to go out and get others elsewhere if WotC didn't provide it. Such a simple thing to do that I don't know why the suggestion should cause controversy. (Not suggesting I mean you by any stretch.)Agreed.
My concern is that nearly all of the ones that appear to represent the various levels of "generic mage" have these non-spell special abilities.
Thats all.
I find it funny that so many people got worked up about the "cancelling the OGL" thing, and yet when the idea is broached to go get the product they want that uses that OGL that they were defending for so vociferously, it's met with a wall.
