I'm saying a shotgun isn't a viable option as they will likely kill you before you're close enough unless you're good and they're bad OR if you get lucky and they don't see you somehow. OBVIOUSLY it's POSSIBLE to kill ANYBODY with a shotgun. I see any other roaming super/Defender at close range I pull out my shotgun and say: "Maybe... I'll give it a shot..." ...Some success. I see a Stormcaller at close range I say: "Shit. I'm probably dead..." ...Very little success.
