PP arc elementalist/slayer next level

Hoping I might get some input about how to get this character to the next level. All content down except uber elder which I believe is doable but would require excellent gameplay. I've been trying to figure out a way to squeeze some more survive-ability out for 1 shots and I dont know if a few more life nodes are going to do the trick.
