Being able to nova ram snubs and have a guaranteed kill means they're in a decent spot right now, you can still mine to kill them since you usually out armor them, and in addition most bombers have hellfire arcs that will mess up a fighter.
By themselves most ships wouldn't be able to take on other ships if we're talking just about stats, but anyone can ramkill which is still a 1shot for snubs that ends encounters nearly immediately. So the scatterguns didn't fulfill their purpose and ended up being an OP fighter gun, in their current state they're fine as much as I wish I could troll snubs with those busted guns again.
