Man, I wish we could get Alkaloid in this build somehow, I really do tend to use it fairly often to help teammates. Even if we drop PBU and keep the set under Tactics, we don't have the slots for Alkaloid - either that or we lose the defense bonuses from the Gaussian's set if we steal the slots. This also has pretty much as many Winter pieces as you can get and you can only attack with Pistols and Bullet Rain if you run a Positron's TF. Only movement power is at 49. Downsides and upsides to this. Would love to see this build in action if you have the means.
