So guys, maybe you could help me figuring this one out.. What are the SUPPOSED blacksmithing levels/perks in relation to the character actual level?
For example:
Iron smithing should go from smithing 20-40, and character level 1-10
Steel smithing, smithing 40-50, char level 10-15

and so on..

It's a RP perspective, I know you can get to 100 smithing at level 1, I was just wondering on a role playing base

Bumpety bump

Don't buy iron or leather, use just what you find...this way you don't exploit and everything is fine.

Oh god, I kinda wish people in real life did this. I will not exploit my PhD to get enormous salary!

It's seems pretty clear to me. The game envisages that you will have smithing appropriate to the sort of gear that drops at your level. So, Dwarven smithing requires 30 smithing, and Dwarven gear starts dropping around level 12; Orcish is smithing 50 and level 25; Daedric is smithing 100 and level 48.
