im not complitly sure but i can say that sneak its a bit disturbing on this game...i dont know whats ur lvl on sneak, but i can walk past some guards in the day and they dont notice me...i have sneak on 72 aprox. and i dont need to take any torch....this means 2 things.
First, i dont know if the torches make a diference, but i dont need to take them away, it makes no diference for me, i can sneak without problem.
so if u want a skill to take torches from the distance, then u need the torches to MAKE A REAL diference.
in Second, they might change a bit the sneak ability coz its what i said, when im on sneak i can stand in some place, and a guard or someone walk right past me, like 1 foot away, and they dont see me, unless u make something to call his atention. i think this is something to look for a few modifications.
