There was no reason whatsoever to nerf mini boss and boss damage from machine guns by 21%. They were just fine the way they were and didn't break the game in any way. Some ppl would much rather use machine guns over grenade launchers anyway. I hate grenade launchers. I don't care how good they are. They're only useful against targets that are large and slow. Try hitting a small, flying wizard mini boss or any quick moving, small aerial target with a GL that doesn't have proximity detonation. It doesnt work and proximities got nerfed so bad that using them destroys your damage.
