Energy/Elec Blaster, Elec Mastery or Mu Mastery, suggestions?

[LonePhantom777]

So I'm trying to get the most bang for my buck out of an Energy/Elec Blaster whose theme is using fulgurkinesis to harness particles into ionic energy blasts. Mu Mastery or Elec Mastery would be his Epic Pool power, and he has Medicine for helping team-mates or himself in a pinch.

I'd like some advice for making a build that can REALLY kick some ass. I'm presently looking to put together enhancements for the MIDs build I've got attached below, but I'd like to hear a second opinion. Care to weigh in, anyone?
