Sorry for the rookie question, but is there really a difference in the armor types other than the abilities you can unlock with skill points?
I mean, I've been using medium armor on my NB thinking that it gives decent armor and would afford me a bit more mobility than heavy armor (I like to sneak and such); but when I put on pieces of heavy armor I don't notice a difference, really. Is it just my mind or is it just worth it to pay attention to the perks or a particular piece of armor?
