Lots of good options, I'd personally get Psi because WoC and CA look nice when active together. Synaptic Overload should stack pretty well with WoC, and it does work great with end drains(First few attacks are on their allies, and then they're out of endurance). Having both Psionic Tornado and Psychic Shockwave is also nice.

I went with ice on my Elec/Psi, and it has been great. I am perma-domination, so sleet comes up every fight. The resistance debuff helps greatly with your damage dealing, and i am loving horafrost. I don't need anymore end sapping since they will get drained dry with conductive aura plus drain psyche
Interesting, thanks for the replies. Both the AOEs in ice make mobs do the House of Pain?
I like to play my //Ice Doms a lot.
I don't like //Psi as much. I haven't given it a fair shot though. Might make a second/third build for a few of my doms to include it.

So I'm creeping my Elec/Psi dom close to the magic lvl 41. I am however torn between which Epic or Patron set to choose.
I know Ice is a popular one for its AOE carnage. Curious if World of Confusion would be viable as well to stack confuse with Synaptic Overload. Mu also seems like a good choice in being able to use Surge of Power and the healing MU. Ghost widows sets are always very good (IMO).
So I'm torn and curious if anything has an incredible amount of synergy?
