The point is, when you has good armor rating on the 3 type of defense, normal minions will usually just do peanuts damage on you. That 100 damage will most likely only happen once in a blue moon with some bosses only. Using your armor enchantment slot on reflection that base on chances, I would rather had a firm raise on the armor ratings. Rank 9 enchantments already raise 10 armor rating, and materials are easily to get as well. With armors that comes with 2 or 3 enchantment slot, you can easily get some good defense out from the enchantments.
