If they did something OPTIMAL, or even something INTERESTING AND UNUSUAL, I'd be all for it -- even in the main book. Since they seem incapable of either, let's put these sub-standard NPCs in a web thing that won't interfere with my paid-for page count.
I'd enjoy monstrous NPCs much more than humanoids. The humanoids I can make myself, easily, thanks. But seeing a Succubus Blackguard 10 -- that's a cool idea, which I would not have thought up myself. That's what I'd like to pay for... (of course, that example came from a free message board...).
Cheers, -- N
