With a good build, this toon will be scary good pvp-wise for duels. Ignore the naysayers above, they just havnt lost to a good elec blast yet.
I wont remake the build for you but have a few points that I can relate from pvp'in several Elec blasts successfully (never/mm tho).
*I would not take thunderous blast, it used to be relevant in arena, but no longer. Take swift instead.
*I dont like snipes in duels, ive seen them work in rare occasions, I think the slots will be used better in other powers.
*Add more slots to Tactics, and Tesla Cage
* Forget about the rectified reticle IO, they work best in Tactics anyhow
That should get you started. But basically, I can see you playing this toon where you KB, or hold your foe, before going melee to use your pbaoe's. Itll work.
have fun,
