It's a bit of a side-track of the original proposal, for which I apologize, but yes - I agree. Right now, the LAO feat chain rewards you entirely too much for wearing a Mithril Chain Shirt, already a good choice in several ways. If I were to re-design a similar feat chain, I'd have LAO just give +1 Armour, -1 ACP (min 0), and ILAO +1 Max Dex, -1 ACP (min 0) flat; making them interesting feats for light armour wearers, with LAO being interesting for all, and progressive utility to higher-level characters capable of boosting their DEX for ILAO, without giving (in my opinion) undue rewards for MCS wearers, but also without sacrificing much of their utility and flavor.
