Protection Warrior
Rotation
Opener: Charge in, Bloodrage, Defensive Stance, Sunder Armor ×2, Shield Slam, then Revenge when it lights.
Priority: Shield Slam > Revenge > Sunder Armor (to 5) > Heroic Strike as a rage dump. Thunder Clap and Demoralizing Shout on cooldown against melee packs; taunt swaps only on fixates.
Cooldowns: Shield Block before every big hit, Shield Wall for the burn, Last Stand as a second life.
Forever notes: Forever: Defensive Stance threat is 80% (up from 30%), so you no longer need to over-gear your DPS to hold threat. Concussion Blow is your interrupt and emergency stun.
Stats
Stamina and Defense (toward 440 at 60), then Dodge, Parry and Block Value, then Strength for threat and Hit to 9%.
Shield Slam scales with Block Value, so a good shield is a threat upgrade, not just a survival one.
