Personally I liked 3.0 DR. 3.5 DR is almost ridiculous to me. If a creature has DR 30/magic a level 7 PC to LV 20 PC can bypass it. If DR is DR/magic it becomes almost useless. And it is almost easy to get your weapon keyed to an alignment. So special material is the only important thing you need to consider, in terms of DR (and what melee PC doesnt carry both a +1 cold iron and silver weapon with them at all times, at least the melee PC that does the most damage [especially after level 10 when they can easily afford these items]?) I personally Dm with 3.0 edition DR rules. A creature with DR/+3 is a much biggerr threat to a level 8 party than DR/magic. What do you guys think about the change form 3.0 to 3.5?
