All I really heard about it was that Daisy would be played by a different actress and that Mandy Patinkin wouldn't be back

While both are true, it's not as big of a deal as you think it would be. The New!Daisy is perfect in her role (and maybe even better cast considering Daisy's backstory). I missed Rube, but his absence is the very thing that drove the story along so you just have to accept it. That said, everyone else was back and in top form.
