Pretty sure its because the new extreme dungeons are more "extremish" than the last ones... Yesterday I went for the first time to THE STONE VIGIL an man, as a ilvl99 war got some pretty nasty hits from dragons, I got some hits around 2700!! With that you need to watch carefully for hate, as a whm or sch healing, at sometime they are going to take hate if you don't roll between targets.

Pretty fun! Speed runs are good for myths but this new dungeons are pretty badass
