Depends how you see it
One time I was playing airsoft and my gun kept curving the bullet to the right. It was a faulty gun, but you can get used to it by aiming slightly to the left, which was effective enough, but where this gun really excelled was when someone was cowering behind something. Turn the gun on its side, and the curve would go up and then eventually down. You can’t do that with a normal airsoft gun.
What at first glance feels like a fault, can actually be turned to your advantage, with a little creativity.
