I have never, ever been in a match where someone just runs around shoulder charging everyone. And shotties are not hit or miss. If they see you, and they have a shotgun out, they will kill you. End of story. And making throwing knives a OHK would be op as hell. Unless they seriously tweaked them, any decent player would have an unlimited supply of instant death blades. Plus unlike SC, you don't have to put yourself in harms way to use them, and you can use them any time. Shoulder charge is fine where it's at. If you get killed by it, it's because you made a mistake, not because it's op.
