BD is Int/Dis. Blink strike is a great melee but generally you don't need it often. Arc blade you want to have ready before the other team's supers so it loses 1v1 to most supers. And skip grenades are damn good, you want them often for breaching/applying pressure or when finishing off someone behind cover.
NStalker is kinda tricky. I would say Dis/Str except Graviton doesn't roll D/S. The Shade step + Keen scout is pretty crucial imo, so you need to invest something into Int which is okay. You can actually get Tier 1 Int, Tier 4 Dis, and Tier 5 Str with Graviton which is the best build imo.
Chest pieces with elemental armor and sniper ammo, boots with rockets and either Last Hope or Second Wind. BD can use Trials helm with revive Super energy and Crest for the exotic. I just got the new Tarantella from an engram so I'm excited to try it out with my BD. I saw Rubenov using one yesterday so hopefully it's good.
All Titan and Warlock subclasses are max Int/Dis for me which is much easier to manage.
