It'll still do that at 80, with resil. My main has about 19k hp and 600 resil and wheN i encounter a survival hunter I go to half HP almost instantly. They will kill me in 5 seconds without healing. So I pretty much flame shock -> bomb heals on main -> lava burst, and if he wants to pop a bunch of cooldowns, disappear, feign death and use 15 other ways to interrupt my spells well then I'm bombing heals until he runs out, it's like the rhino boss, forget about it...
