The fact that so many cutscenes are tied to long resting shouldn't be used to argue against (or for) a proposed resting system. There are a total of what, 4 cutscenes that actually require a long rest? The dream sequence(s?), Astarion, Lae'zel trying to kill you, and the post-grove-raid party. All others could be changed to: "next time you visit camp" or "next time you talk with a character" or even "next time you short rest."
We're proposing change here, so unless you actively like so many cutscenes being tied only to long resting, it shouldn't really weigh into discussions because the "cutscene upon rest" mechanic can also be changed.
I like the idea of there being restrictions to long resting, especially
I'm not sure about that but I guess the "until next short rest" is not really possible considering that you can short rest everywhere. Same about "next time you talk with a character".
I may be wrong but I think that the models and the camera are fixed for every cutscenes in camp (or mini camp) to avoid wierd cinematics.
If I'm not wrong, "next time you visit camp" is the only possibility left. Which mean long resting way too much... Or short resting at camp too...
