Elec/Elec/MU because I can laugh at my three most hated villain groups. Carnies, Malta, and Awakened. My build is weird in that I actually took Rune of Protection. Yeah I know not optimal. But it is fun. I roll in grab some aggro... use energize if I have to. Then RoP if things get hairy. Then barrier if that doesn't do the trick. by the time barrier wears off energize is up. In a pinch use power surge... then cycle barrier before power surge drops, powersink to refill endurance, energize, re-toggle and get back to smashing. I play with a ton of recharge and Electric armor has some built in, so I rarely ever have to use RoP, but it does happen. Even though Elec Armor provides some PSI protection, it's not bullet proof. Popping RoP puts me near the cap. I'm fairly unkillable and I can dish some serious AoE damage. My only real complaint is that single target damage is a bit low.
