Here's how I see it Shotguns take less skill than sniping does. Why? It's obvious to everyone including shotgun users that they are very strong currently that's not saying it takes no skill (although not much) to use a shotgun. People with shotguns can be very skilled in terms of how effectively they take advantage of movement and range. With snipers your already at a disadvantage with most people running pulse/shotty and killing so quickly where you need to have good aim good awareness without third eye be mindful of range a lot of variables come to sniping which makes it tougher and therefore harder to be successful with taking more skill.
