I just hit 23 on my electric char... and now I don't know what I want to take next. I've got, as far as I can tell, everything important already, and I'm looking to increase how sustained my output is and make myself harder to kill mostly.

Current powers:
SS Rec/End
Electric Bolt
Chain Lightning-Lightning Helix
Sparkstorm-Electric Personality
Electric Form-R2
Gigabolt
Lightning Storm-Stolen Thunder
Ionic Reverb
Electric Sheath-Matter-Energy Union


My initial thoughts are:
Field Surge, possibly with Power Swell as a second emergency-shield (Plus, being an active defense, it can even be used at the same time as Sheath, or right after)
Electrocute-I could use a disable, and it also lets me debuff the target and has a 100% proc of Ions, and can set up Lightning Arc for single-target output (That doesn't destroy my energy pool like Gigabolt and Lightning Storm do)
Ball Lightning to increase the number of sustained damage sources I can have online at once (On top of my two storms, which is already pretty fun for large groups)

Possibly down the road (i.e., at level 26) I was considering Mindful Reinforcement as yet another damage shield/heal, plus it has an energy return advantage, and I can't get enough energy.

I'm probably going to get all of these eventually anyways, but I'm not set on that, and I might be forgetting something really useful too.
