Focus on skill power on your gear, not just electronics, and whatever abilities you most use. My electronics build is more of dps healing, with a sniper and smg in case anybody gets too close. I'm a little squishy but it's more of a team build not a solo build. And my sticky bomb is maxed out at 250 000, so don't push any higher (about 43,000 skill power). Focus your talents on your skill cooldowns and durations and you'll always have a ammo/heal/revive station, and you can switch between tons of BFB stickies to kill SO much, or have endless flashbangs... That's pretty fun too.
