Advice/critique of Champion ROA build

I want to make a nice, tanky, Champion ROA build. I know there's probably better ascendancy and/or ways to play ROA, but I just wanted to do my own thing. Revolves around using The Tempest Longbow and stacking as much flat ele (lightning, some cold from herald to shatter) as possible.

Could anyone check my POB and help me out please. Ignore rolls and damage. What I'm looking for is more of advice on set up and any ideas you think would improve what I'm going for.

Edit: Forgot to make it Vaal ROA

Damn, didn't even notice that eva life node tbh lol That's how long it's been since I've played on that side of the tree. You don't think it's worth it then to go to scion area for the life and att speed?

Gonna have to google that ammy, haven't heard of it before. Have you had experience with it?
