Only the PC can smith well, improve armor/weapons, etc... the most legendary smith in all of Skyrim can’t even sharpen a Skyforge Steelsword past what I can do at level 8...
Only the PC can enchant items... not even Farengar the esteemed enchanter of Whiterun can place the lowest enchantment on an item of mine despite my gold...
It hurts the role-play possibilities and realism IMO... how can the PC be the only one in Skyrim who can improve Orcish armor? The ONLY person who will enchant items... not realistic, not RP friendly... and before you say it is for balance... please... charge insane amounts of money for these skills if need be, and if money is too easy to come by then that is where the balance is missing...
