There were parts of the game designed around traversal in the dark with a torch, sacrificing your left hand weapon (shield, whatever) for the torch a la Tomb of the Giants. They also continued to hype the lighting engine for the game and those sections.
With the lighting gone, the torch is now pretty useless unless you want an orange color in the room instead of gray.
This is why I don't believe pre-release stuffs from PR since most them will be a simply bullshots. Isn't the beta have similar impression on torch carrying?
