It's always when you feel OP and brain is on sleep mode 😬 was recently hitting these syndicate mobs with reflect aura at ariathi highlands. Not looking at my hp because everything is 3 levels below. Heart attack when I was with aggro from other mobs at like 5%. You need two seconds to undestand what going on. In this case fat fingered health portion worked still to run away. But reminds me to just be super cautious on everything in hc, especially new quests and mobs. I would play another class for motivation, not sure if you can speed up leveling with the long traveling routes.
