They will either need to add more powerful Moon Druid Exclusive forms or tone back the forms Land Druids can get I think (and uh give the animals the stats they are supposed to, like multi attack), cause otherwise the two Subclasses are fairly balanced and closish to what they are supposed to except for the discrepancy in forms.
I'd probably just make dire wolf and giant spider exclusive to moon druid. Giant badger is decent but doesn't have the HP to really stick it out in a big fight, so it leaves land druids in a decent spot where they have some combat forms to fall back on but mostly want them from the utility of what those forms can do while the moon druid wants the actual combat power.
I'd probably add more in general, but yeah that sounds like a good start. Maybe give both Boar, Squirrel, Normal Wolf, Panther, Elk, and Goat, maybe even centipede and snake. And then to the moon add in Lion, Tiger, eagle, and uh maybe some big bug?
