Electric is weak for everyone. I try and try to play it, I am drawn to it, and it invariably disappoints (not as much as say Kinetic Melee, but really....). Electric is a one-trick pony: Lightning Rod. Its a nifty trick but still a singular one.
Damage.
525 damage, followed by 525 damage, followed by 673 damage (or thereabouts)...at level 40, with two IOs slotted (the +3 Defense ones) and everything else SOs, solo play. Blasters have to use their T9s with Build Up or snipe for high damage, Brutes have to get a head of steam going, and Scrappers...just have to keep swinging and the magic happens. And as noted above, you get more reliable in churning out the damage.
Now, back to my baby Brute....
