Also about the eye boss.If you're ranged there you can attack corner at the back of the room to the left and hide behind the rock if he targets you.You wont be in line of sight so his focus ranged attacks cant hit you.Most reason tanks die is because even though there is a cast bar that shows for the 360 swing they dont bother moving.Its the mentality of if there's no red aoe so i dont need to move.
