To the poster above, you are not wrong exactly. Between levels 2 to 9 Moon Druid is objectively worse than 2 other subclasses.

However, worst class in game? That's a bit harsh, you still get full spells and don’t get fatigued like berserker barbarian.

As for the op, my advice is to play a different class, subclass or install a mod. Currently Moon Druids are too gimmicky to use.
