It was insane. I have a similar story with a troll rogue. Dude had insane hp regen and it was basically my mana bar versus his skill at disengaging to regen. Got down to 2% health and finally got a proc off on him to end it. He died in one hit that was around 280k I think? It was nuts. I was a healer. Azeroth was my place too. Lok’Tar Ogar!
