A build would help a ton. Also, you think voltaic is really going to help you destroy AV's? :/
Off the top of my head, Voltaic means your elec assault. meaning your damage is already meh. And if you want debuffs, go with ice mastery for sleet. it counts as a pet and will do much more -res/-def than poisonous ray since it doesnt follow the dom modifiers. I could be wrong but I think its about twice as much more.
If you have the funds for it, may I suggest just using a 2nd build? Keep your current favorite build for use against regular mission content and add a 2nd AV soloing build that you can change to when soloing AVs is desired.

Long story short, I'm doing a minor respec of my (only) Dominator in an effort to squeeze out enough performance to solo AV's and such. That said, my main efforts have been slightly higher global recharge (to offset the switch from Agility Partial Core to either Intuition Partial Radial or Musculature Total Core), slightly higher global damage bonus, and significantly higher S/L/E Defense (though losing some Res), and adding two more pets (Voltaic Sentinel, and the Tarantula from Mace Mastery).
Now, my question is... Since I switched from Mu Mastery to Mace, I'll be crying for several weeks at losing Ball Lightning (arguably one of my all-time favorite attacks in the game), one of only two AoE's I had, leaving me with only one real AoE attack, Static Discharge. This leaves me with two options: Keeping in mind my AV-solo'ing desires, should I take Poisonous Ray for the -18.75% Resistance, or Disruptor Burst for a lesser replacement for Ball Lightning? Neither of them are spectacular powers, and I'll hate the far-too-lenghty draw/animation time on either of them (since they are the same), so really it just comes down to...
With the lengthy draw/animation time and weaksauce damage (a bit over half the damage of my "main blast") in mind, is the -Res worth the sacrifices? Or would I be better off taking the AoE, using a shorter attack chain for AV's, and only use the AoE when necessary?
Thanks in advance for any advice!
Edit: If it helps, Poisonous Ray would be slotted with 4 Devastations and a Decimation Acc/End/Rech. Disruptor Blast would have 4 Javelin Volley and a Force Feedback proc.
