My primary weapons are useless. I am doing ok, but only with shotguns, grenades and Supers. Was trying to use a 293 Scout Rifle which is very good in crucible, and an auto rifle haven't won a single shoot out. You would think the difference between 300 and 290 is only about 3%, and isn't that big a deal in PVE, but apparently in Iron Banner it's a massive difference.
