While part of me enjoys some aspect of different material types providing different AR values, I just don't think the middle ground (where we are now) is ideal. I like green leather armor, and I know there are dye tubs but there's no spined or horned hues on the tubs. I like black chainmail and sometimes blue or green but I'm not going to wear shit AR just for personal appearance. I like the concept of all the magical bonuses that came in, around AoS, but I don't think there's a good fit for that here without making things really messy. What I propose is that all armor be normalized regardless of material type. Leather, horned, spined and barbed could all produce the same exact AR level, opening up the market for those products so folks can choose their style without suffering a penalty in AR value for it. Same goes for metal armors where if you want the best (crafted) you need valorite. This basically kills the bottom end of crafted armor and completely shafts the fashion aspect (which we all know is very significant in UO). TL: DR = Convert material AR values to Second Age style where AR is based solely on the item type and crafting quality level.
