MerricB said:With regard to the Armour providing Damage Reduction concept: It's something I don't like. One of the chief reasons I don't like it is because it causes a major overhaul of the entire damage system. Consider a fighter wearing Chainmail. Let's say this is DR 5. What then does this fighter have to fear from Kobolds? At d6-1 damage, they're only ever going to hurt me on a Critical Hit! To make these weaker creatures useful again, you have to, once more, go through every creature in the Monster Manual and increase their damage codes. Ugh. Meanwhile, if you're a wizard (low AC in any case), your hit dice is suddenly even less useful than before. The overall effect of adding Damage Reduction as a feature of normal armour is as massive as any previous change in D&D. It undermines the familiar combat system to a great degree. Cheers!
Yep, that's about the size of it. I have DM's who house rule armor as DR, and it's exquisitely lame. They don't beef up the kobolds, of course--we just never fight anything with attacks that do less than 2d6 damage. Rather, every foe is a brutal heavy-hitter who tears right through the DR. In fact, they've even decided it's a good idea to give all characters Power Attack as a free feat.
