i would argue the polar opposite to this - conductive aura is -the- defining power within elec control. it carries the entire set and is the primary reason to chose elec control. without it, there’s not much in the powerset of particular interest
static field is an obvious power to drop given that it doesn’t do much and is bugged. dropping one of the immobs would also be a sensible move given they’re not overly useful, preferrably the AoE immob given it's rarely applied in a useful manner
@JonelethStar - on some of your other attacks, consider whether 5 slotting a purple set including the damage proc + a damage proc from another set will still give you the defense set bonuses you’re looking for, the extra damage procs will up your outout slightly. for example on vicious slash, 5 slot hecatomb and then also put in mako’s chance for damage
overall, whilst building for defense isn't my sort of thing the build doesn't look too bad. you'll find refinements through continuous play and your own perefences will shape what you want in the final build
