Elec/Stone build help?

Don't have mids now, but I will give some general advice with Elec/Earth doms...

The powers that I use frequently are (in this order):
Chain Fences, Conductive Aura, Tesla Cage, Synaptic Overload, Static Field, and Paralyzing Blast from Elec.

Seismic Smash, Power Boost, Heavy Mallet, Stone Mallet, Fissure, and Tremor from Earth Assault.

I had originally thought that Mud Pots would be awesome since you're already in melee most of the time, but the range is too small and the end cost is too high to be worth it.

I originally had Jolting Chain, but dropped it fairly soon after I started picking up powers like static field, the hammer powers, and tremor.

I actually like Tremor, especially when leveling up and before permadom because slotting a force feedback proc gives you a nice little boost in recharge, and it's quite a bit of control since you can cast it often.

I would suggest slotting the AoE immobilize with end mod. instead of immob duration. That way, when you hit power boost and chain fences, the mobs lose about 1/3 of their endurance. Combined with Conductive Aura, they are drained very quickly.

I took the Ice mastery APP mainly for sleet and the defense shield. If you can stack up a fair amount of S/L defense, around 25-30%, when you hit power boost (which you typically do before jumping into the spawn), it puts you pretty close to the soft cap for long enough to get them locked down.
