Opinion on this build!

I'm planning to do frezing pulse with good survival, criticisms are appreciated

Sup!
I'm doing the same build,but with Eldritch Battery.
I guess you wasted many important points.
In shield i don't like it because i use tempest shield,but it's optional. I really don't like it so much because you have so many nodes to get elemental resist and cap at 75% very quickly.
i took off the wasted points so you can get more usefull stats, so here it is:

Since you got Shock, i guess you're using add lghtning damage on your freezing pulse.
Your build is very good, i just think you wasted some points, but everyone does the things like they want.

thx for advice.
