Electric/electric/? dominator

[Loquis]

I'm running an electric/electric dominator and looking for a good fit for the epic power pool.

I'm currently leaning towards energy, but I'm not totally sold on it either.

I should add that I'm mainly soloing with him.

Actually leveling one up myself. I am not good at building builds myself yet, especially with this class. But if anyone can help it would be appreciated.

Thematically, I like Mu Mastery. You can pick up Ball Lightning for more AoE damage plus Charged Armor. Other than that, Ice and Fire are quite good.
