Resonance subclass (credits to the artist)

I recently saw a post on Instagram showing concepts for a third subclass of darkness that would be the resonance (credits to the guy) which is based on the bosses we have already seen like Calus or Ruhlk. In my opinion it would be fantastic to see something like this in the game, but here’s the “problem” i see. When we approach the first encounter with the witness in the last mission of the campaign he offers us to join the final shape and become a disciple (thus getting the resonance), an offer that we reject and indirectly rejecting the resonance. I would really like to see them bring a third darkness subclass and I think resonance has a lot of potential. There was just one thought that came to mind. What do you think?
