My Electric/Electric Dominator, Elec/Psi Dominator and my Elec/Elec BLASTER all disagree...
My Blaster regular drained Mobs to little to no end.. and kept them there..
Same, generally speaking.
I, too, had a Kin/Elec/NRG Defender, and while noticeably less effective post-ED vs. pre-ED, it was still a damn deadly toon.
Tank takes Alpha - jump in, Power Build Up + a slotted Short Circuit = mobs @ 0 END, LT's at effectively 0 END, and Bosses damn close. Ball Lightning, Transfusion + Transference (all with 1-2 EndMod's) equaled Boss at 0 (no sense hitting the LT's, they're dead before it makes a difference)/EB hurting/AV with a chunk off. Not what it was pre-ED but a definite boon to teams for sure. Cycle SC, BL, and both TF's (with PBU as it comes off CD) and before you can blink the EB/AV is stuck in Brawl-only mode.
Slow going solo for sure, but in a team - egads, the "Watch the Blaster tank!" carnage! As if a /Kin didn't already provide enough...
