Extra forms:
-Bear is weaker than dire wolf and no pack tactics.
-Dire Raven is a great scout and that's about it.
-Sabretooth Tiger is solid and can knock enemies prone, but only comes online at level 6.
Lunar Mend is Terrible, you're better off using short rest or have somebody else heal you like healing word, etc.
Being able to wildshape as a bonus action is the only good thing, but you could always be in Animal form prior to the fight.
Weird take, but okay.
Bear has more HP and a stronger attack than Wolf, so that's just plain wrong.
Comparing Lunar Mend to short resting is ridiculous - one is obviously meant to be used in-combat, while the other is just as obviously out-of-combat. Lunar Mend is pretty decent bonus action healing. Sure, Healing Word with a +5 spellcasting modifier is nice, but Lunar Mend outscales it at higher spell levels. It also maintains nice action economy - in Wildshape, you're not often going to have a bonus action available other than Lunar Mend while your spell slots are just sitting there unused. Might as well be self-sufficient and free up the bonus actions and spell slots of whomever you were counting on to cast that Healing Word.
Being able to Wildshape as a bonus action IS a good thing. If you're low on HP and don't want to eat a spell slot, you can drop your Wildshape as a free action and re-Wildshape, all while staying in the middle of the action with your action ready to use for attacking. That's a FULL HEAL from a bonus action that recharges on short rest. Nobody else does that.
Overall, it sounds like you haven't embraced the bestial Swiss Army Knife. A bit of bugfixing would be nice so that Moon Druids had a few more options with the Moonbeam/Call Lightning spells. If anything, I wish Moon Druids got one more Wildshape charge so that I wasn't using half of my combat resources during exploration tasks, similar to how a number of ritual spells work for out-of-combat usage.
