I am not the right person to answer this. I've played there but once. Several others are way way way more familiar with the course than I am.
Nevertheless, I do see greatness in those golf holes, or at least three out of the four. Of course this is gonna turn on how one defines "great." I shall explain.
#3 - it really is one hell of a great golf hole and it goes far beyond what you say. The green isn't a simple back to front slope, but rather has shoulders off the bunkers and other more subtle breaks, making it just a monster to putt. Also miss it and any chip/pitch is going to be very, very tough. Playing as long as it does, it just falls into such a brutally tough category that I believe that, combined with the history there (Casper laying up, etc.) is enough to connote greatness.
#7 - what you're missing is that the green is very raised - it's a strange shot in a course otherwised filled with greens more flat to the land. It's also a rare short approach shot on that course, and you expect it to be easy... but then you are zinged. Perhaps tough to call it "great" in the world-class context, but nevertheless it is a fun, tricky, surprisingly tough golf hole. I like it a lot.
#10 - enough has been written on this, not much for me to add. I have posted here ad nauseam that I don't see the world-class greatness - I was underwhelmed playing it and I do think 3 is a better golf hole - but even I admit the green is freakin' brilliant. Others can add more, hopefully.
#13 - I didn't see much greatness there either.
So 3 out of 4 are very, very good golf holes. If one wants to say each is world-class great, the argument is easy against that, I think. But 3 and 10 each come very very close, if not actually meet the standard. Then you think of them as a group, and well... the list of courses with par threes as a group better than WF-W would be short indeed.
