There's never a situation with current animal form tuning where the HP of your humanoid form or your allies is less valuable than the HP of your animal form. If you're left with a spare bonus action, you use it to push or jump for easier positioning for backstab anyways. It's like saying Sacred Flame has a situation if you refuse to use the abundantly superior option on Shadowheart of a crossbow+1, that hits more reliably, does more damage, and can be amplified with fire dipping or poison coating. Sure, you can use it if you're fond of using vastly suboptimal options, but it doesn't mean it's horribly balanced and should be addressed, because the fact is a cleric relying on a crossbow for their damage instead of their class defining cantrip is just stupid.
Perhaps but like you said, currently. Maybe future animal forms will be more valuable. I am not stating Lunar Mend is a good heal at this moment. I am just stating it serves a different purpose in a different situation.
And I really think a lot of your opinion of attacks and damage is skewed due to the mixing of Larian mechanics and 5e. You're right, in it's current state, it's a mess. No question. But you are analyzing Larian systems within 5e systems and concluding 5e is bad. 5e is bad if it gets mixed with Larian homebrew.
Sacred Flame and light crossbows do the same damage, albeit crossbows can also benefit from modifier bonuses. But Sacred Flame is unlimited and at level 5 bumps to 2d8 damage while crossbow stays the same. In standard 5e rules, crossbows ultimately become inferior to cantrips other than for martial classes. You are then conflating Larian rules of dipping, backstab, height advantage which yes, makes certain attacks much weaker. That's what many here are complaining about.
You want to toss out 5e because you don't see it being very balanced in BG3. I am asking you critique 5e on it's own merits and you'll find it's fairly well balanced. The balance is off not because of 5e. It's off because we have a hybrid.
