Nope, doesn't need to be realigned also lockpicking and pickpocketing SHOULDN'T be the same tree, it makes literally no sense.
You refute the basic premise for this thread and then fail to give any reason as to why. THAT literally makes no sense.
I would say that of all the skill trees, Blacksmithing is the absolute worst. Every single perk you spend in that tree, with the exception of the arcane blacksmith, ceases to be of any use once you get a perk higher in the tree. They really should have treated Blacksmithing like they did the other 2 crafting trees and made it so the intial perk was a five part percentage increase in how much you could improve armor and weapons. I think then the challenge becomes filling the tree with perks. Obviously, Arcane Blacksmith could stay, then I would move Fists of Steel into Smithing, so everyone could receive the benefit of increased unarmed damage regardless of armor choice. Some interesting perk choices could then be added into this tree, or even some utility options, such as making a perk that allows you to sharpen or reinforce a piece of armor in the wild, adding a small temporary damage or protection boost, or maybe add a perk like Toughness or Muscles of a Smith, that increases armor or damage by a small percentage, to reflect how working a forge gives you increased physical power. Dragon armor should remain the top tier perk, because it is very fitting for the dragonborn to be able to craft armor from the creatures he slays.
I think doing this would change the tree from feeling like a waste of points into something more worthwhile. All the other armor besides Dragon should just be unlocked as your skill progresses (Elven/Dwarven at 30, Orcish/Steel Plate at 50 etc.) The way they changed point accumulation in smithing, this is actually an incredibly viable alternative to the current model, because leveling smithing is no longer a joke and requires a lot more of a material and time investment instead of spamming iron daggers. I would appreciate anyone's thoughts on this model.
