Did you know that we have a talent that makes it 20%? Great we can now continue with this number.
Did you know that enrage is not active 100% of the time? Great we actually don't take this extra damage all the time.
Did you know that we have about 30% more hp than everybody? Wow 30 - 20 = 10 ! We are actually tankier than most classes !
Did you know we have a spell called "Commanding shout" ? Wow, we have a raid wide survivability buff !
Did you know that bloodthirst heals you ? That is 4% of your health every 4 seconds and can restore a millions of health during a fight !
Did you know we have "Enraged regeneration" ? Oh I've got an idea ! let's use this + Commanding shout at the same time for crazy damage reduction + then heal back up against an unavoidable burst mechanic !
The only time I died on my warrior is when the whole group died, so if it is unplayable to you, just, learn to play?
