One of my mains (Kin/Elec Offender) was in Pinball Wizards, an all Kinetics SG on Freedom and Virtue back in the day.
I do not know your playstyle but maybe first try your build with common IOs first then figure out what effects you're trying to obtain with set IOs.
Additionally, you really don't need the snipe (Zapp). I'd swap that out for Tesla Cage so you can hold a target to use transfusion and transference on. If you really want the snipe then add it in post fulcrum shift.
Charged Bolts is a skippable lackluster blast, Lightning Bolt is better. Siphon Power (is a great single target +damage power) used in combination with Siphon speed it slows and weakens targets. Allowing your single target blast to do more damage.
Also siphon speed is a fantastic travel power/enhancer. Under Leadership I would focus on adding an EndRedx to those toggles. I would also take Assault over Maneuvers and save that defense for Vengeance. Someone is going to faceplant, why not use them for a great team buff? That's what the Nemesis do! ;D
Ball Lightning and Short Circuit are a great AOE combo. Slot up for damage and end mod. Keep in mind that Kin Elec is a great end draining powersets.
Get hasten sooner...much, much sooner. You'll need that recharge prior to speed boost.
If you're really concerned about end and you're on teams, slot your Speed Boost for recharge and tell folks on the tem to pass you their blue inspirations. Alsl slot an EndRdx into Transference during the early levels.
You could also get Recall Friend instead of the Fighting pool to port dead bodies for Vengeance...I'm just saying... Teammates are useful face down or standing up.
Also why no Inertial Reduction (PBAoE, Team +Jump) Increase Density (Ranged (Targeted AoE), Ally +Res(Smash, Energy, Disorient, Hold, Immobilize, Knockback)? Those are great buffs!
Once you have Transference you really won't need to worry about end at all. Voltaic Sentinel is an okay pseudo pet but as I recall it appears next to the caster and draws aggro. It's great for a Stormy with all their keep away powers but VS may destroy a target you're trying to buff from.
Those are my two cents....Overall Kin/Elec was one of my favorite combos to play! ;D
