Oh yeah I saw that already yesterday. KSG seems pretty good, only saw one hitmarker out of 3 videos I watched of it (the hitmarker happened at such an extremely far distance, so I ignored that). You've got to aim really well, it does require a lot of skill and rewards you for it.

I had saw another video of the KSG, but it got deleted almost immediately.

The ksg appears to be the only good shotgun.  The other shotguns are absolutely garbage when shot from the hip.  The only redeeming factor is a really tight ads spread on all of them.  but that also means that shotgunning is going to get slowed down significantly.

The pumps need a buff. Big time. Any close quarters hit with a shotgun would splatter someone. BUFF THE SHOTGUNS.
