Hey there! I'll add to what others have said in saying thanks for taking the time and effort to write up detailed feedback like this. Even though much of what you raise has been brought up and chewed over by other people, every single individual write up like this, that another player comes to of their own accord, is another point of data, and it's all worthwhile.

I agree and second attention being drawn to most of the issues you bring up here; though I have to say, buckle in for more of those extreme face close-ups that add nothing to the story and don't convey anything of value. Larian is deeply in love with them at the moment, and it compounds their already poor cinematography and scene choreography. Myself and others have spoken at length about this, if you're interested:

Regarding losing companions and not being able to travel to camp:

The game does NOT communicate that you can do this and it's very unclear - to the extent that I know many others have submitted bugs reports about it, or felt forced to reload... but, you can fast travel to the camp without going to "Take a long rest", using the normal fast travel system - you arrive in the camp during the "day", and going this way won't block you from traveling with a dead companion. This is how you're supposed to go back and fix a character that fell down a pit, but the game does not give you that information clearly enough.

Anyhow, thanks again for taking the time and effort to do this! Every report matters, especially ones that are well thought out and clearly reasoned.
