Any arguments send to that guy will just bounce off his massive ego. It's pointless.
On-topic: Auto-healing is never a good idea in my opinion. It makes games far too easy. I like old school games, where you couldn't hide in a corner to avoid danger and healing over time.
Modern shooters are the worst. Get hit, hide behind a rock, regain full health. Old school shooters had you turn a level upsidedown for that one medkit that would get you through the rest of the level.
Most classic rpg's are hard and do not forgive errors. I think Larian wanted to capture this trait in this game. Still, without the need for mana, resting or any other spellcasting limitation, it's still too easy.
Anyway, this game in particular has plenty of healing spells and potions. Just use those potions as much as you need them, because you'll be finding lots of them, and ofcourse you can create more yourself.
Give one of your characters 1 point in Hydro and take a healing spell with you. Man-at-arms has a nice healing spell too. You'll be able to start every fight at full health, every time.
You're also free to sleep in any bed you come across. I suggest Mayor Cecil's bed. It's really fluffy.
