Need help for my Lightning Strike CI Crit Dagger

So I've been trying to create my own build for a while, but when I played my last character (Got to lv 50) it felt slightly weak at the point when I died (I should mention I died to my game freezing, and not actually any fault of my own at that exact moment), so I'd like to hear if some of you have ideas or suggestions for the build, as I will be trying it again.



So the idea is: Run Lightning Strike, shock-stack stuff with high crit chance and be tough with the help of Tempest Shield, Life Leech on Energy Shield and Arctic Armour. I could also be running 6 Power Charges later on, and eventually grab Conduit if my party needed it.
I am still debating whether Iron Reflexes is worth it or not, but it allows me to go for Vaal Pact later, if it should be needed, plus it seems like a waste to let all of the % Increased Evasion Rating go to waste.



So the problem I had at this point was a lack of damage, mostly. I was planning to go for From the Shadows and Arcing Blows next to solve that issue, but I was also having serious issues with armour which only reduced damage with about 34%, because of the new Cast when Damage Taken changes, which took away my Molten Shield.





With these links and items I was running 733.4 DPS at the end of Act 3 Cruel, which is substantially lower than what my previous EK character did (around 1100DPS), but I was running with 2487 Life, which is higher than my previous EK character, so it evens out slightly.
I wasn't going to change out my Mightflay until about level 60, but maybe that would've been the solution

Any ideas or suggestions that could improve my build are very welcome.

Too many life nodes, not enough damage nodes. Try this

Also, don't run LS with LMP, replace LMP with faster attack.
