I don't know what point you thought I was making, but my point was, more kingdoms lack draw cards and need more card draw than lack nonterminals and need a card draw made nonterminal. Obviously Lost Arts is incredibly powerful and in the contrived scenario where you have Lab, Smithy, Pathfinding, and Lost Arts, you should Lost Arts Smithy. But I'm saying Pathfinding more often makes a difference - you sometimes don't need Lost Arts, but you so very rarely skip Pathfinding.
Ah, so you're comparing these two scenarios:
There is a terminal draw you can Lost Arts but there isn't a cantrip you can Pathfind
There is a cantrip you can Pathfind but there isn't a terminal draw you can Lost Arts
and concluding that Pathfinding is better than Lost Arts solely because scenario #2 is more common. That's not a very good method of comparing the two, because not only are you comparing a rare edge case against another rare edge case and ignoring the more common situation in which both nonterminals and drawers are present, you are also comparing the way in which Pathfinding is used almost every time against the way in which Lost Arts is used maybe 30-60% of the time.
The thing is, buying Lost Arts is almost always strictly better than gaining 4-5 Villages for free (because you have guaranteed collision if you're putting it on a terminal, which you don't necessarily have to do by the way). Buying Pathfinding is almost always strictly worse than gaining 5 Labs for free (because you have to spend gains on stuff you wouldn't have wanted so many copies of otherwise, aka cantrips). 5 Labs for free are nice, but you don't actually buy 5 Labs per game very often, whereas you do actually buy 5 splitters per game very often. In other words, Lost Arts quite directly reduces the number of gains you need to build your deck by 3-4, and Pathfinding doesn't do quite that.
So the question is what is better- More game warping or less skippable?
That's not really a question worth anyone's time, though. It doesn't make any difference. If both of them are present in a given kingdom, you don't care whether or not one of them is less skippable in other kingdoms. What's more important to consider is the practical in-game reasons that make them stronger or weaker, because that'll affect how you build your deck (and it's the reasons that are important to consider, your conclusion is not that important either).
