If you wanted to stay at range, you picked the wrong primary. Static Field + Conductive Aura and the use of chaining powers rather tan cones means Electric Control is at its best in the thick of things. Grav/energy and Mind/Energy are quite good ranged doms, though Fiery Assault is a little better than Energy at ranged attacks. Of course, Energy Assault is quite good at melee damage, and Dominators are actually slightly stronger in melee (1.05 melee damage modifier versus 0.95 ranged)
In terms of skippable powers:
The ST Immob is optional - it stops knockback, so you'll need to be careful using it, as Energy Assault gains quite a lot from knocking people around.
Between Static Field, Synaptic Overload, and Conductive Aura you've already got very good area control. Paralysing Blast isn't all that necessary, though it could be nice to stop extra spawns.
Gremlins are universally considered the worst control set pet to date, but they're still absolutely worth taking.
As far as /Energy goes, the snipe is, of course, skippable, and three of the first four attacks should be plenty. You can skip any one of them, but they each have their strengths, so look at each of them.
If you want a fully ranged dom go mind/fire.
Hey folks just need some help I made my first dominator, I made a elec/nrg dominator. Elec cause it is new and flashy, and energy cause I love big orange numbers. My question is what can I skip out of elec and nrg. I think I am going to try to be a range dominator and shy away from bone smasher and total focus. Even tho Total Focus will be hard to skip. Any help would be great and thanks ahead of time.
When I die, I want to go peacefully like my Grandfather did, in his sleep -- not screaming, like the passengers in his car.
