Protection Offtank Build: Damage Theory
I don't think I've seen much threads talking about a dedicated Warrior Protection offtank build and rotation.
I'm suggesting this particular build: (4/15/52).
This is based on taking the Fury shout talents to increase the effectiveness of Battle/Commanding Shouts, as well as picking up Puncture on purpose as opposed to ignoring it altogether.
By "Damage Theory", I mean using primarily Devastates to proc Sword and Board and using Shield Slam when it's up--while being in Berserker Stance to reduce threat output. Pair this with gear that successfully satisfies the 540 Defense skill requirement and high SBV+Strength, and the Protection offtank can possibly have a respectable damage output, more so than the conventional Protection tank. TC talents and Shockwave are taken to help with AoE tanking.
