DK Self Healing Based on Damage Taken?
So last night a friend asked if the DK tank tier was worth it and I mentioned that I had heard that the 5% to Death Strike helps with shield/healing. He pointed out to me that DK healing off of Death Strike is based on damage taken. And according to the tool tip he's correct. http://www.wowhead.com/spell=49998
So if the tier bonus is 5% damage increase to DS (for 2 pieces), http://www.wowhead.com/item=60350; is it worth it. What's the benefit other then threat?
Blood shield gives a shield of 50% of the amount healed through DS, http://www.wowhead.com/spell=77513, but DS's heal is based on damage taken.
Is the tool tip wrong? I'm confused.
