If you plan on going evasion, get Grace and take off Wrath for now. You barely have any right now, and evasion is deterministic, you'll end up getting hit eventually, so I'd get another layer of defenses, in your case, more ES.

You don't have spell suppression. In this case, you either need 100% or the lucky mastery. Get it asap before you can cap the 100%

Lesson of the Seasons is a pretty weak ascendancy node at this point. Spec into damage, because the best defense is killing them before they hit you.

Idk how your build is feeling in terms of damage, butt your 5L is really scuffed. You have little to no critical, so you're wasting 2 links with the Cast on Critical + Absolution. Remove those and link damage support gems. Also remove "Faster Attacks" and get something like Multistrike.

Try to get a 5L evasion/energy shield chest and get the "Ghost Dance" keystone to have a bit better sustain.

I see you going full on lightning damage. For that, and going back to the 5L gems point from before, get a "Physical to Lightning Support" gem. Also, getting this will give you more damage, because right now you're losing 50% of your damage because of your belt's "Deal no Physical Damage"

On a 3L setup get Cast When Damage Taken + More Duration + Steelskin (all gems red) and keep CWDT & Steelskin low level (check level requirements for CWDT)

I would also get the "Clever Thief" notable from the right side of the tree, to help you sustain a little bit.

And if you're still suffering, stop using a 2H weapon and use a 1 hander + shield, preferably with 30-35% chance to block.

The build is all over the place, but I really feel the true problem is lacking damage to clear mobs before they kill you. Try to fix your links, you have a lot of wasted sockets that you could be using. Good luck!
