OK! Well, I guess it comes down to what you mean by "completely collapse". I enjoy the BGA leaderboards, but only got to the top 50 or so when I was actively trying.
I agree that you're going to discard 3/4 of your artifacts, and ~50% of them are almost never worth playing. But I've been continuously surprised by people pulling out wins with PoP/artifact combinations I didn't expect to be viable.
If your definition of "completely collapses" is "some paths are much better than others in high level play", then I guess we just disagree on what makes a good heavy board game.
I do agree with you that Wingspan has a corvidae problem, though; I've never seen anyone but a beginner lose with an early raven.
