I guess I'll try the drone one first with Shock. Yeah, I do notice the Rocket Drone backing away. I thought it was leading them away or something. LOL
I don't think I'll start Platinum anytime soon. I'll do that once I actually have a banner (any would work) and have unlocked all the characters. I have a few UR, which I don't know what to do with. Black Widow, Saber, and pretty sure I have a Scorpion. I'm still waiting for Harrier or Typhoon.
Although if you feel you need the extra fitness then yes, take points out of drone. A 4/6/6/4/6 build would work pretty good as well.
This is the one that I use. I take Drone to detonate because it can be a decent distraction at times, and the rank 4 capacity bonus in the passive is nice for holding slightly heavier weapons. I still get full shields, and because I'm focused on tech combos anyway, the loss of the additional capacity/power damage/weapon damage isn't a huge issue.
I roll a 6/6/6/5/3 shock drone and it works nicely, though it's obviously not as good a boss magnet as it used to be. Still good for trolling enemies and keeping them somewhat occupied. You could also go 6/6/6/6/0 if you're feeling confident. Especially on gold, the extra shields and health hardly make a difference anyway.
Alternate between incinerate/overload to cause constant power combos. For everything else, Mattock, lightweight, high accuracy, good damage. Acolyte is there for shield breaking against enemies resistant to powers (collectors, phantoms) and enemies with too much shield (atlas, banshee, prime)
My first and favorite build. Has never steered me wrong... Very good team synergy too.
The drone is really good at distracting primes and creating fire explosions. Pick explosive drone. If you do invest more than 4 points into combat drone, make sure not to pick any of the shield upgrades - you want your drone as weak as possible to get more frequent explosions.
The Wraith, Talon, CSMG are good choices. Incendiary ammo is a godsend. I personally run with a Saber. Stun mooks with chain overload + headshot. Fire explosions using incendiary ammo, incinerate and occasionally combat drone.
