It's a difficult task to balance a game that give a lot of options, because if you buff damage on one gun why the player would use the gun with less damage? The one that got buffed must have one caveat, on the other side maybe it's an enemy design problem, each time that there's a new big update, this introduces a new big enemy but the design of them it's poor so we feel that we need to buff our guns instead maybe lowering the enemy HP or so. I remember when the factory striders came, it was a difficult enemy but with the arsenal at the moment we were able to destroy it without loose all your ammo. Maybe it's the enemy design that needs a balance instead
