He is reducing the grind, which I guess you might dislike, but the majority of people find that to be a relief. I for one have spent over 30+ hours on the game, which I would love under normal circumstances but the fact is a big chunk of that was just grinding and not progressing in the game. Despite this, the majority of the content is repeatable, and he's even adding a gallery so hopefully, you can find that as consolation.

But other than that he is just fixing bugs, and revamping the graphics and mechanics of the game. Not removing much, just adding and improving what's already existing.
