The only "problem" is that most of the maps are small and conducive to shotgun use. I use a shotgun and usually Vex. When I see people charging me, I back pedal and use Vex and destroy them. A shotgun should kill someone in one shot at close range. Don't let them get to close range. Where Bungie could help would be to make more maps that benefit the use of longer range weapons. Truthfully, it's a no win situation because people are going to cry no matter what. If there were more big maps, people would cry about Snipers and Scout rifles needing to be nerfed.
