War1911 obviously did one of two things.
He either went into a mission at boss-end with side-kickable teammates to see ER like that ( was seven or so levels above the AV's ) or he's an out and out liar, (Like a good republican ) and he simply made those statements sans the actual facts in the matter.
War, don't make claims like that and then a blanket statement like "play past 16th before you try to talk like you know something." The arguments put forth here by the true tesla gods are insightful and pertinent.
ED does very little in combat, mostly because combat is too swift to take into account their drain, and partially because as stated, AV's will go down firing their best shot at you, regardless of ED drain. Thus there is very little reason to slot anything but damage. The Electric blaster's only saving grace at this point is a TC that as we all know won't work on most combatants who are bosses or better.
