Dying as soon as the animal form hits 0HP opposite to the rules of 5th edition
I agree moon druid currently struggles (haven’t played land yet), and for me that’s mainly because concentration breaks too easily and key spells that a moon druid should be able to reactivate even in wildshape are disabled in animal form (heat metal, moonbeam, chain lightning). Sure the animal forms aren’t great up to level 5, but I’m happy to wait for the owlbear at level 6 and better forms later if the magic is there to supplement weaker beast forms early on. There’s plenty of chat about the class on these forums if you’re interested.
But your quote above implies your character died when their wildshape HP was exhausted, which shouldn’t happen and my druid always just reverted to human. Might you have come across this bug:
