I'm only a few hours into the game, and I couldn't agree more with the notion that short rests should be increased (2 times between long rests seems good to me), and long rests should be limited somehow.
Adding some realism to resting would be nice. Perhaps 8 hours of game time has to pass before you can long rest again?
Larian could add a "realism mode" which caters to this issue. That way, people who prefer to cheese their way through the game can still do so.
