Delicate Synth is bonkers and way too good, though Prep is a culprit too. Its main strength is that it's almost a second Brygots with Strides that doesn't consume IQ. 200% is huge.

The IQ "nerf" doesn't seem very well thought out. We reach cap so early in the craft and this is still the first tier of the expansion.
PbP and Muscle Memory are dying abilities now.

The lv80 skills seem completely pointless. I'm baffled what they were thinking with those.

Reuse is also another baffling design. The interaction with Reclaim is so obvious I can't tell if they intended it, or if they handed ShB DoH design over to someone who's never done crafting. A lot of casual crafters still haven't caught on to just how good this ability is. It's a goldmine.
