D3-FNC is such a good support build, and makes most activities really easy!
I've chosen to run my build with the House as the primary with Destructive and Predatory - Both top tier PVE talents. Without having to "waste" a skill on a less than mediocre first aid skill you can still regenerate health when you get kills.
I've paired it with Flashbang Sticky since it's probably the best skill for PVE and for sure the best form of CC there is.
The secondary is a 182 GS Navy MP-5 N which I rarely use, but IF I need to "farm" back the signature skill I'll swap to this and get the finishing blow on a few NPCs.
The talents are also pretty self explanatory: Combat Medic -> Heals your teammates and your shield, On The Move -> Always moving so you'll get even tankier, Precision -> Nice crit and crit damage, One Is None -> Up close and shooting the NPCs in the head.
At 9k Stam and 121k SP the shield health is a whopping 2.350.001, just think about that (pretty sure there's no point in going above 121k SP and that that is the "cap" for the progression of shield health - I know some go to 125k but I'm sticking at 121k).
