The expert recipes may be fairly difficult to hit the max collectability on, though they missed the mark on rewards, and because you can do an easier craft to get points, the issue of people who want the top spot just spamming crafts (or botting) also exists.

It's mostly what I expected. I don't see a good reason to do them more than to try and hit the max collectability a couple of times and then you're done, because if it's heavily RNG based, grinding out leaderboard points is going to be all about 45k+ or whoever plays the most. I think these missed the mark.
