And, as I mentioned in one of those other threads, I've not played moon druid in the full release yet, though I did do a playthrough in EA.
My two biggest problems with the class, much as I enjoyed it, were (a) not being able to activate/move concentration spells like heat metal, call lightning & moonbeam when in wildshape and, (b) the ridicuous ease with which concentration is lost in BG3 which affects all classes but moon druids disproportionately given they are more reliant on concentration spells as they can't cast in wildshape. If just those two things were fixed, along with the bug that means you have to re-equip items after wildshaping to regain their benefits, for me the moon druid would be hugely improved.
By level 5, it was also much in need of some better wildshapes, but not having tried what we get in the full release I'm not yet able to comment on how far that's provided.
Btw, in my current playthrough I've just seen some armour that does look tailored for moon druids so I'll be aiming to get that once I get round to replaying my EA moon druid in the full release. For anyone who hasn't come across it, it's in Act 3 and ...
Available from Voiceless Penitent Bareki near the Undercity Ruins Waypoint underneath the Lower City. It's only 11 base AC, but gives an extra +2 AC and advantage on saving throws vs spells (might help with concentration!) that it says remains active in Wild Shape. Plus 22 temporary HP on casting Wild Shape and -1 to damage while the temporary HP are present. Assuming that all works as described, it sounds pretty useful!
