It all depends on map, game type honestly. I'm making a video on this today, like and subscribe:
Sure any weapon will work, but if you want to maximize your effectiveness you need different kids for different maps. Here's what I like, but it's honestly up to you and what feels good for you.
My all purpose build A:
Kinetic: Hand Cannon (Judgement, Dire Promise, Better Devils)
Energy: Ranged Weapon (Tone Patrol, Positive Outlook, Uriels, Last Perdition)
Power: Whatever tickles your fancy, I use any sniper with snapshot sights, Sins, or The Colony.
Kinetic Reload Mod
Energy Recoil Mod
All purpose build B:
Kinetic: Ranged Weapon (Vigilance Wing, Nameless Midnight, etc)
Energy: Annual Skate, Stochastic Variable, or Prosecutor
Power: Whatever floats your boat
Aggressive non hand cannon build:
Kinetic: New City
Energy: Positive Outlook or Uriel's
Power: Colony, Play of the Game, or any launcher
My long range build (I get crazy high K/D with this for some reason)
Kinetic: Nameless Midnight or Garden Progeny
Energy: Prosecutor
Power: Maxim XI or LR2 or Long Walk
Like I said, I have a video uploading tonight on this if you're interested.
