I’ll be trying out a level 80 build based on the thread linked below:
Based on the first video the skill points he used are these:

Based on that I’ll simply throw points into things that should either increase damage, increase her survivability, or misc.
This variant, using level 80, increases normal damage by adding accelerate and minds eye. But if you’re a fan of more elemental damage, you could throw in Cloud Kill.

Or if you feel you need more survival, then consider some of the skills in the middle tree such as recompense or elated.
I’ll let you know how it goes.
