About breaking down doors.
Strength check is good for warriors.
But consider other parties.
4 mages? Currently they can use their cantrips to destroy a door.
4 thieves? It would take time, but still they can destroy a door with their knives.
Suggestion - leave the HP, but also implement strength check to break down a door with one hit, if a blunt weapon is equipped.
Larian gave players a lot of options to get around doors in Divinity 2 and I'm already seeing that in BG3. Also, there is always the chance that a mage will pass the skill check too.
The reason I would like HP removed is that it would speed up gameplay in slow moments and give Larian opportunities to add humor into the game. Imagine having a half-orc barbarian complain that they were defeated by a door.
In tabletop the player can be rewarded with a funny outcome from a natural 1, I haven't really seen any of that in early access. It's a big part of the charm in DnD and it'd be great for BG3 to have some of that same charm.
