So probably one of the greatest mods from Oblivion, even though it was simple, was the ability to drop torches on the ground, so if you were a melee character without night-eye or light spells at your disposle, you could still go through dungeons without sacrificing the ability to use a shield or 2h weapon.
I haven't done much reading up on skyrim, so I might have missed something addressing this, but what would you think of the ability to either place torches, or create like a sort of fire in certain areas, instead of running around with a torch in your hand
