"Enchanting skill gone"
You say this despite the fact that you can still enchant items. Do you imply that you would leave Oblivions enchanting system exactly as it is, only with a chance to fail? Imagine closing an Oblivion gate, climb the tower, grab the sigil, get an awesome enchantment, then fail at applying it to an item because your skill is too low. You also don't need medium armor. Most armors in any real or fictional setting are either going to be heavy or light. Spears I agree, but if Bethesda added spears, you'd be whining about no throwing darts. If we're going to attack TES4 for not having spears, are we going to attack TES3 for not having flails?
