Absolutley not Grimnarash!! That is the worst advice ever! Leveling as a protection warrior in vanilla will slow you down INSANELY! If you watched "Lore" from ZamOfficial, you can hear him in an episode talking about leveling in vanilla as a protection warrior, and it was brutal.
Your damage will be severely reduced, while the talents do not provide that much extra survivability compared to the damage increase you get from the DPS specs.
It is 100% best to go with either Arms or Fury depending on playstyle and weapons that you may have.
Protection/tanking on retail is so far from what is was in Vanilla that it can not be compared in anyway. Even if you go back to any of the expansions, Vanilla tanking was something of it's own.
