I agree in the idea of perks, but I also feel that the armor types themselves should have more variety to them. For example I don't want an unarmoured fellow to somehow sustain a large portion of damage from magically just being good at taking hits from a weapon, but rather the advantage lie in the lack of armor not weighing down his movements granting a bonus to striking speed and so on.
I would be happy if they simply remove armor skills. I would aprove also if what armor skill or perks do is reduce the movement penalties that armor gives, without altering protection in any way.
It seems to me that having only one armor skill entirely defeats the purpose of having armor skills to begin with. As the main benefit of having armor skills in the game is to allows players to define what sort of armor their character should wear, and actually encourage them to wear that, instead of just wearing whatever has the best stats, regardless of whether it's leather armor or a heavy metal plate suit. If you're going to hace armor skills at all, you need to have at least light and heavy armor. Given that Bethesda has reduced the amount of skills from Oblivion and added at least one skill that wasn't in it, though, I could see armor skills getting removed. If this is the case, though I'd say replacing them with perks is a good idea, though I'd be fine with them reducing any penalties caused by wearing armor rather than actually enhancing the defense of armor. It does seem to make more sense for armor skills, or perks, to behave that way.
Honestly not sure about removing it as a skill, but I am sure I agree with what these guys have to say.
