I honestly dont see why anyone would get light armor, with the heavy armor perk it makes heavy armor weigh nothing, same as light armor, and with muffled boots, well you are well off without any sort of light armor. What the hell is the point of it? Same goes for food, never even have to bother doing any of that when you have potions at hand, I have found I have never had to eat a single thing in all my playtime of Skyrim.
So go ahead, tell me any pros of light armor over heavy armor?
Edit: Not to mention the light armor perks are all for increasing the armor rating of light armor (what the heck for? might as well use heavy armor if your looking for armor rating).
