>>6452332The Delphi have been shown with many different looks in different sketches and concepts. Look, there's even one with a smooth humanoid hand here. Like I said, there's never been a definitive production one, and furthermore, Matt could easily have changed his mind or redesigned them since. tl;dr: there's really no telling what we're in for, or whether it even will be the Delphi.
There's no point in getting down on it before it's even fully revealed. If you break down say, a Glyan or Buildman into its component parts, most of them pretty abstract and "samey" too. They all fall under Onell's general aesthetic, just as intended.
