Has the Orion EVER got nerfed?

Sure as soon as you give us no bullet drop on our sniper rifles, tanks, shotguns, etc.

Deal.

People are only crying over Orion cuz its the highest dps LMG VS have and it was given as default.
Personally I hate the gun cuz of its low magazine and ammo pool, I usually go for Flare or Ursa with extended magazines so I can mow down entire squads without reload.
Thou I can see how people that only get 1-2 kills per life would prefer Orion and that its a unfair gun to have as default (but its most certainly balanced).

People who average 10+ kills per life also prefer the Orion.

Anyone that knows how to aim for the head also prefer the Orion.

If that data includes periods both before and after nerfs then it's useless.

You're really grasping at straws here.

To answer the OP's question, yes but obviously not enough because you're still complaining about it.
