This is my Hybrid "Anti-Striker" build that I commonly use in the DZ and Skirmish.
The EMP Sticky has a Cooldown of just over 10 seconds and my Defib heals for more than 370K on allies.
Sure the build is rather squishy if you just look at the stamina and toughness values but the vigorous vest does wonders here.
Due to the usage of the Defibrillator you can keep yourself fully overhealed before you engage someone so you sit at 1.5 times your health right away.
Its a fun group build and can be used against multiple sets like Striker / Reclaimer / Firecrest / Tactician etc.
(Basically everything that frequently uses skills or loses their bonuses when EMPed like Striker does)
It's also very fun in PvE although I recommend swapping the EMP sticky for either the Flashbang mod or a Pulse.
As an added bonus you can diffuse any incoming grenade and toss them right back at the enemy!
My personal experience is a lot of fun with this build although I have to warn anyone that wants to try this out:
It has a rather steep skill ceiling, you will have to make good use of you teammates and make sure you stay out of the line-of-fire to make the best of it.
Try to stay close to your teammates though so you can help them with heals and more importantly the diffuses.
