I've been playing around with a moon druid and comparing it to the 5e version. The polar bear is weird. I get it if they want to nerf the wildshape, as the brown bear is pretty powerful at level 2, but a polar bear? Why not a black bear? Druids can only turn into animals they've seen. I think Tav is more likely to have seen a black bear than a polar bear. Aesthetically, the polar bear seems out of place in the green forests in act 1.

Wildshape itself is also wrong. I read somewhere that Sven said he thinks you should be able to wildshape into one form while in another. Hard agree. You should be able to do that. Take a look at the core rules regarding druids. The official rules of wildshape in the PHB say that druids retain their race and class abilities in their animal form. I should be able to wildshape into one animal while wildshaped as another. They can't cast spells in wildshape, but they can maintain concentration AND use actions related to their spells. I should be able to reapply heat metal or move my moon beam while in wildshape form. None of these things can be done in Baldur's Gate 3.

The fact that Sven said that he wants druids to be able to wildshape while in animal form is good. Perhaps they're working on implementing it. Go the extra step, and add in all the other stuff.
