If you happen to wonder what are plate armors are for, then they are the armor which are worn by Death Knights, Warrior and Paladins.
As time goes by, you will definitely hone your expertise when it comes to blacksmithing, and soon, you will tend to realize if ever you will specialize in Armor Blacksmith or Weapon Blacksmith. You will have a lot of access if you choose to specialize in Armor Blacksmith such as access to plans that will allow blacksmiths to create weapons, and this goes the other way around too.
