yeah shotgun seems like the most useless weapon in the game. And I dont like the rocket launcher much, other than for shooting down helicopters. Its way too slow. People that complain about grenades or grenade launcher or c4 being too powerful probably dont use them often, because if you miss, reload takes forever, or to throw another grenade. Also if you are in too close and someone comes up on you quickly which happens often, those weapons are useless. Still they have uses, which makes them balanced in my mind.
