I didn't main anything either. I never played PVP competitively(because let's face it, this is the least competitive multiplayer out there), I played when there was nothing left to do with my group back in the days where weapon usage was vast(ok except pulse rifles really) and vex would murder you in 3 shots. That at least took some form of using your brain to not die by anything instantly, now it's about who can hold down the right trigger the longest lol.
