Each gun can perfectly kill guardians just as easy as the next (unless of course you are using a crappy pulse rifle that is not red death) Just stop. Stop. Staaaaahhhhp. Its rude to say but if you keep getting killed because of some "overpowered gun" you probably just need to get better at the multiplayer. And dont bring up the vex mythoclast because that is the most difficult gun to get so it should be the best of the best. Just because you dont raid doesnt mean ruin our hard earned weapons. Quit whining...
