Yes. We're talking about an NPC.
Obviously, that was not clear to me. Now, I know that's what you meant; I've stated how my perception bears on this particular situation. If the character is the greatest swords smith in the world, I'm alright with plot-devicing him, knowing I could set his skill to whatever I need it to be.
However, this is a bit of an extraordinary situation. I don't consider encounters with the "world's greatest sword smith" to be any sort of a litmus test. Meeting craftsmen in villages and cities to perform needed tasks is far more the norm. And, as stated, I still maintain that having a system in place for NPCs is a convenience to qualify the scope of their abilities.
Even if I did, what does it matter? As you have proven in your last post, no matter how much I explain "I was not clear in saying something else", you will insist on arguing that I said something else because "That's what the thread is about".
From where I am standing, it appears you were backpedalling from the stated purpose of the thread. Even if you weren't, I've already stated that feats occupy a different role than feats, so I'm not sure why you brought it back up.
Because, as I have been saying since the first post, it's not "I don't like it; it shouldn't be there". It's "I don't think a vast majority even use it. SO it shouldn't be there."
Well, you won't be able to demonstrate that, but I think it's incorrect. If you dropped the word "vast", I might have shrugged my shoulders and said maybe.
Even if so, I really think KM has my proxy on this issue: that good games are best served serving a variety of tastes.
Your thesis question was "should games have such skills?". I think they should. When you asked the question were you genuinely interested in hearing the positions of other posters to learn why they thing so? Or were you only interested in shouting them down? Because from the last quoted paragraph, that's how it's looking.
But maybe it's late and you are getting grumpy and you ought to try again in the morning?
Again, back to the thunderstones, guns and psionics. Whether it's in stock fantasy or not doesn't matter. It's use, not presence.
To repeat myself from the last post, IMO something as ubiquitous in fantasy as capabilities represented by the craft and profession skills and adding as much flexibility to the game as those do certainly deserves a place in the core books more than thunderstones, guns, and even (yes) psionics.
