So ever since I noticed the weight of heavy armour in book 2, it's been bugging me. I had some intention of switching a few pieces of my light armour for better heavier armour, but for the most part I've found that I'm better off just waiting a little while until I can find some decent light armour. At the worst, light armour was 2 points behind heavy armour and a fifth of the weight; yet for half the game (I guess was lucky with a chest) I was walking around with dragon hide armour which was better than any heavy armour I'd seen and weighed less than any heavy armour and even my supposedly light armour pants. Anyways, I've managed to think of some suggestions that might be a possible fix, plus a few other suggestions about things I'd like to see in book 3.
1. Heavy armour needs a notably, consistantly higher armour rating than light armour.
2. The most prohibitive aspect of heavy armour was its weight compared with light armour. As anyone who has ever carried a piece of armour a long distance then tried wearing it instead can tell you, it is a lot easier to wear the armour than carry it because the weight is more evenly distributed. What if the weight of worn armour didn't count towards the encumbrance limit? Instead why not have heavier armours have more of a nonproficiency penalty so that more armour skill is required to wear the armour without penalty? You could also have heavier armours with lower weight/penalty than other heavy armours with a similar armour rating to show that these armours are better crafted.
At this point, I'm just going to reference this thread
, and note that your opinion is shared by others (including me!) - I too feel that there's not enough Light Armor/Heavy Armor differential in Books I/II, and hope it's made greater in Book III, so there are actually tangible benefits for going with Heavy Armor over Light Armor. Because, right now, I really don't feel like Heavy Armor makes sense as a choice over Light, for many of the reasons you indicated...
