Here's my Elec/Elec/Soul, so you can make changes as seen fit. The thing to look at imo, is my resists are better 75% S/L/E, almost 66% F/C (with the Reactive Proc, that will get to 73% with enough damage), the other resists are better too, and it also has 100% Slow Resist.
I wouldn't have slotted a lot of the ways you did. Stamina = Performance Shifter: +End Proc, Power Transfer: End Mod & +Heal Proc. I'd likely slot Physical Perfection the same way. So that's just 3 slots each.
Combat Jumping: LotG: +RCH, both +Resist IOs and a Kismet.
I don't know why you're taking Flurry. Build Up would just be +Build Up Proc.
6 slot Lightning Field with Superior Scrapper's Strike. You want to move the Critical Strikes +50% Crit Chance Proc to an actual attack (I have forgotten which attack is best suited for it, I don't believe it was Charged Brawl, but I did that for some reason outside of being the best, and I don't recall why at this moment)
There's just some quick observation on the build at this moment
