I would like it if Larian made 2 possibilities to take a long rest:

1. A basecamp where all your companions are. When you rest here it pushes certain story elements further. obviously it has a fast travel point.
2. A backpack camp with the partymembers you are travelling with. Camping in dungeons or on the road may or may not trigger random combat encounters depending on your survival/perception skill.

For me it doesn't make sense from a roleplaying perspective when I'm in a dungeon I travel all the way back to a bascecamp and trigger story-plots just to take a long rest. I want the immersion and excitement of take the chance to long rest in the dungeon I'm exploring.
