"The creature statistics section of the 2024 Player’s Handbook will include more Beast options than the 2014 book contains."
For me, how they implement this sentence is going to be what makes or breaks the Druid. And sadly, they seem not to be showing their hand before publication.
They are making it so complex compared to other classes:
a. non-moon druids will have up to 12 beast stat blocks with CRs of 1/4, 1/2 or 1.
b. moon druids additionally will have up to 12 stat blocks with CRs of 1-6.
There will not be 96 beasts in the PHB (nor should there be). But:
i. I want there to be cool options to work up to (someone mentioned the CR 8 T-Rex, which won't happen, but Triceratops or Mammoth is achievable); and
ii. I want to have viable forms that gain in power as I level up, so that I can choose always to keep the same shape, be it a wolf or bear or whatever.
For both of those to happen, we need the option of rooting through the MM to find weird new forms (i.; that's there now, thankfullt requireing DM permission), but also 8 different forms of some of the land animals we had to start (wolf, bear, and maybe six versions of the flyers). It's going to need space in the appendix to the PHB to allow that sort of flexibility. Even if they excluded Moon druids from consideration, having three versions (cr 1/4, 1/2, and 1) of a half dozen basic forms would be needed for me to buy into this.
