Compared to PnP, the Druid of the Moon bear is awful.
Here is the Brown Bear statblock from Roll20: https://roll20.net/compendium/dnd5e/Brown%20Bear
The tooltip doesn't take into account that the Strength becomes that of the beast, the bear only has a claw attack in the game. Not to mention that this bear lacks Multiattack. The Brown Bear form is one of the most iconic forms for a Moon Druid in 5e PnP. In addition, that form has 4 more hit points than it has in the game.
I'd suggest adding real statblocks of the beasts from MM to the druid wildshapes available.
