Will a Ele/Ele endurance sapping Dominator stay viable?

Right now I basically roll in with conductive aura, chain fence the group, tesla cage the biggest threat and just zap them constantly(1-2s activates 4-8s recharges unslotted) while the aura depletes them further. Before i'm even done dispatching foes they're writhing around me totally devoid of any endurance and only managing a weak fist attack. It is so disturbingly effective at low levels (conductive aura @ 8) i'm afraid it won't last, but will it?

Also I was thinking Super Speed & Stealth with Teleport (no fly... theme restriction) for those times I need to go Z-axis. What else should I be interested in? (note join date & post count, )

Edit: Poor grammar in title, it should be an not a.. probably residual from reworked title.

No rerolling, I got 4+1 alts and i'm sticking to it!

it would be easier to perma drain them with elec/psi, drain psyches -recov paired with the -recov in your attacks will floor just about anything in about 10 seconds (GMs and AVs take slightly longer maybe 30-60 seconds due to their massive end count and -end resist)

sapping by itself is not enough. You need to combine it with defenses and some other controls.

Enemies seem to be able to attack with very low endurance. I have seen a few posts claim that they don't need the full cost of a power, just 1 point and they can use anything. I dunno if I believe that, but I do know that on my sappers, I keep them flatlined and they still get of some attacks anyway.

Also, as stated, high rank enemies have a huge pool to start. In some cases over 800 points of endurance to blow through. And sapping is an all or nothing protection. If they have enough to attack, you get zero protection from it. So you always eat the full alpha, and often beta and gamma before you have them at zero. At that point the attacks slow but don't stop.

Now, combined with a bit of control and defenses, it is very nice. Just like defense itself, goes best with a bit of resist and a heal for those unlucky streaks. All forms of protection are best in layers. With sapping this is still true.
