Yesterday in Tangled Depths, I waited for some help to do one of the hero challenges, and a while later a warrior flew in and went right to it to start it, so I jumped in as well. The warrior stood in front of this Champion for the entire fight taking everything the Champ could throw at him, and every time I hovered my mouse over the guy he was at full health.When I try to do stuff like that with my warrior, I get killed in like 5 seconds, so what is he doing to be invulnerable? My warrior has almost full yassith armor, but I haven't added agony inscription to any of the pieces yet, and need to add the second piece as well, but still, even with those, is the guy really invulnerable?There was another fight I watched the other day in Auric Basin, where a character pulled the Champion Vinetooth, stood against the back wall, and killed it solo. How is this even possible?
