That's because a lot of people don't think like you and I. They're selfish and delusional way of thinking makes them believe they actually achieved this weapon through some incredible feat when in reality it was given to them (through rng). On top of that, they think this weapon is some "holy grail" that will guarantee them success when in fact the weapon is situational like any other and success is mostly measured by skill and teamwork. Anyway, it is getting nerfed soon so I'm sure attitudes will change, people believe the nerf won't be enough to notice a performance difference but IMO it will definitely be noticed. What would be the point in a nerf if there isn't going to be a noticeable difference?
