Where can i get berserker stance

Berserker Stance BUG. Hi! I'm new here and I don't know why but I've done the warrior quest "The Islander" but when I finished it. 7 Feb Hi, I recently instant leveled my warrior to level 80 and I see there are no Defensive stance or Berserker stance available. in Blizzard's Not A Bug list, Bloodthirst will now benefit from Attack Power granted by Improved Berserker Stance and Unleashed Rage.
