Gambit mainly is where I've done this. And other than that I've used the same weapon on my other account and did just about the same. I dont pvp anymore but when I do i mainly stick to suppression and not kills, so , efficiency isnt going to reflect impact, when I do go for a kill I generally get it. But my main focus is to collect enemies to allow flanking from team mates. I generally die while doing this, and I'm trying to allow the push so, not going for a full perfect paradox to the face and have them scatter. The black scorpion can out gun because it has no range preference, and it never loses tracking. It also has a compass to use with your mini map, So go fk yourself and continue trying to base your counter argument of of irrelevant statistics.
