Epic Enchant: Heroic Sacirifce
I was going to put this on my DB user page but I couldn't edit it.
I chose Reincarnation because it's an act interfering with the natural path of life and death and Divine Intervention because it's an act of god to deny healing penalties from interfering.
I guess you'll see it as an alternate version of Divine Intervention where you heal them instead of bubbling them out of combat.
Given the costs (20% armor durability and removal of the enchant on worn gear) and the Epic Mystic Enchant slot, I don't believe it's too strong.
The idea came to me because when I was running heroics in RDF, some people just died and boss mechanics brought me low, and if the tank who was left had full HP, we might've not had to restart the fight.
Now that I'm writing this on the forum, thinking about how many people use Architect builds, I doubt this would see much use in RDF runs.
*Edit: Please disregard I wrote "cannot cannot" twice in the ME builder (remove 1 of the cannots). hahah
