Should the following "regular tank combo" be 3>2>2 instead of 3>3>3?
"You should then be able to swap back Endurance and just do the regular tanking combo 3 (Encouraging Shout) > 3 > 3 > 1 (Destroy) > 3 > 3 > 2 (Draw Sword) > 3 > 3. Then just repeat this for the rest of the fight, switching between the three mobs for the combo."
