I think these Expert Recipes are pretty good. I'm quite happy with the difficulty that it's currently at. It's true that you do depend on the RNG-driven conditions to do them, but that's the primary idea of how a harder recipe should be.

Most of the times, we need Pliants which greatly saves our CP for durab restoration. But if it doesn't appear early, you can still work around it until it appear later -- you just need to know how to handle a late Pliant! The total number of steps are quite long, so it's only natural that you'll encounter a few Pliants eventually. In the case that you really just got 1 or 2, then maybe really bad luck, and the craft will fail. But otherwise, there's a lot of time/steps for buffering.

The same goes for the all-hated Hasty Touches. Unlike ARR, which 3 to 4 failed Hasty would screw you up completely, here we can fail a bunch of Hasty and it'll still be fine. So even though we always say "actions that do not succeed 100% is a bad idea", it still somewhat works out here since there's a lot of buffering for the failed touches.
