The Artificer Mindsmith: Yay or Nay? (Patreon)

The Mindsmith was a novel idea for an Artificer, and I think there is a trope in fiction that it fits, but I've found it awkward to render as a player idea, and it has not proved widely adopted by players (likely as a result). It was originally conceived as a villainous take on the Artificer, with their powers much more loosely defined (less combat based, more sinister).

I think it still has potential, but I'm wondering what people think - is it a good use of time, or should it be dropped as legacy, with potentially a new subclass being introduced in its place?
