When you can long rest in the middle of the goblin stronghold while in the process of genociding them, is a sign of the current resting mechanics just being temporary.
I would argue Larian should implement a day/night cycle as part of their solution to resting and that this solution should be mindful of the class balance concerns. For me the lack of signs of the passing of time directly detracts from the storyline which dictates there the party is ticking time bombs (twice for Gale).
