I don't play a druid currently (well, I don't play anything but a monk currently because I rarely get to play rather than DM), but I think we have to keep in mind the perspective of those players who actually play druids, most of whom specifically play moon druids and love the fantasy of...well, pretty much exactly what you see in the movie clip.
I think almost everyone is onboard with "but that is OP at low levels" and were expecting a bit of a nerf. But that is not what this change proposes. This change proposes removing that entire playstyle from the game. It's telling all those people that they have been having badwrongfun and there is no place for it in the game.
Moving to generic beast stats has arguments both ways. It definitely simplifies things, though for more devoted players a lot of the fun is building a list of different animals for different purposes, and that would be gone. To me, this is a pros and cons argument (aside from taking away the ability to become a tiny insect, rat, etc. with 1 hp; that is all con and I will never support it because it makes the game way less fun to play).
But removing the extra hit points from wild shape makes moon druids something else entirely.
I have no interest in the argument that "this doesn't feel like what druids should be to me; this should be barbarians, etc." or "this was the wrong call in 2014." That horse left the barn (possibly while wild shaped) 10 years ago. You can't say that you are keeping 5e while changing the fundamental nature of one of the core 5e classes.
I don't think this proposal will fly because look at the pushback it is already getting. This will likely go the way of the revamped critical hits. If it did happen, I would just ignore it and keep using the 2014 PHB. But I would rather have an update that addresses the issue of low-level moon druids without completely gutting the sub-class.
Also, question: under the current proposals...why would you play a druid? The new version of wild shape makes them into a poor fighter, and their spell list is already considered subpar compared to a wizard or cleric. What's the upside of a druid?
Least played class (allegedly) getting massive nerf is a weird look for OneD&D.
