And what's the problem ?
The moon druid looks pretty powerfull from 1-4 and I read a lot of people saying that land is even more (not my feeling but anyway).
The problem is land druids get the same forms and also get additional spells. Moon druids can shape shift with a bonus action but that seems like a bad trade off.
Land druids should not have equivalent forms of moon druids. They are designed to be more spell casters.
