I say use whatever guns you wish, if anyone thinks one holds an advantage, just use the same. Dont nerf anything! There is suppose to be a variety of guns, including weak & strong. The glaring thing that is OP is by far the arc blade of the Hunter. The invincibility is stonger than radiant skin, and they can kill way too many opponents over a large area with the time they have with it. Titans and warlocks have to get lucky enough to get a group in a very tight area to get multi kills.
