I'm running the tactician set at the mo, nearly 100% uptime on my skills at Max power when the 4 piece bonus starts rolling. I really want a Caduceus but I can't find one, anyone know where it drops?

Does anyone know where can I get armor mitigation stats from? Is there specific armor, or does armor mitigation have a different name in the stats?

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.

Triage talent. Make sure all other players have first aid. Stay close enough together so that all players are healing each other. Pulses, flash bangs, seeker mines and turrets for days!

Haven't played much, so excuse my low stats. At the moment, I have about 95K DPS, 85ak Health, and 22K Skill Power. Using a Support Build. Recovery Link, Support Station, and Defiblirators.

Why do you want an electronics build, and what do you plan on doing with it? You don't just create builds just for the sake of doing so. You create builds in order to facilitate a particular way of playing the game. For example, I've been running an LMG-support build. I act as both healer, and team fire-support in end-game content. I set up at the back of the team, and use the volume of fire pumped out by a belt-fed LMG to SUPPRESS enemy movement, and kill anything too stubborn to be suppressed. So I have about equal distribution of points between my three traits (about 2000K). That allows me to do enough damage with the LMG, so that I'm not having to empty the entire magazine in order to kill something. Plus be able to defend myself if a rusher gets close. I have about 65 K health (with 59%) armor mit, so that I can withstand a fair amount of damage. Because using an LMG requires me to stick my head above cover for long periods of time....and the amount of lead and damage I'm sending down range is guaranteed to draw the aggro of enemies. Lastly I run about 21K in my skills (2000 Electronics) because the effectiveness of this build requires that my skills be potent. I rely a lot on Smart Cover to buff my damage, and reduce incoming damage/heal me. Plus the ammo Healing station allows me to fire my weapon, and not consume any ammo from my reserves while its active. Thus allowing me----when set up properly----to literally pour a continuous stream of machine gun fire wherever I choose or its needed. THAT is how you want to approach builds in a game like this. Start from what it was you want to DO...then work BACK to setting your character up to do that thing most powerfully and most efficiently.
