Need help with build Scion Divine Ire, low life, mana, ES

I think im doing something wrong here, I have 8k ES lot of dps but fighting with uber elder is rally tough. I don't know if i need more dmg or more defence :/ If you have any suggestion what can i change here please give me some advice :D

You could probably get a bit more ES but everything seems solid to me. If damage is good maybe drop a support for Energy Leech. Uber Elder is more of a mechanics fight so is it possible you just need to work on that more?
