I didn't know you could take them off walls. No wonder I have so many. I wasn't looking closely and assumed I just had the ability to extinguish them for stealth purposes.
They also have weight again, unlike in Oblivion. Half of a pound, now.
I'd ended up gathering so many torches from bandits I'd killed and other NPCs I'd pick-pocketed, and I noticed that I was able to carry less loot as usual until I noticed how much weight I'd been carrying in torches and promptly dumped them all in storage except for four.
If you're running vanilla settings, you don't really need to use torches; it's never dark enough.
Really? Because I had to turn my brightness setting up in the game, on account of everything still being too dark with using a torch.
Pro tip: What you experience isn't what everyone else experiences. Think about it a little.
