I'm on PC and Shotguns are so rife it's borderline unbearable at times. Even on the larger maps, players will opt for these and hide around corners waiting to pounce. They seem so overpowered that it's nigh-impossible to stop them in any 50-50 situation and for the rest of the time you're treading on eggshells as to where the next shottie user is going to pop out from. Most seem to be using marathon and lightweight perks with SOH so they are moving round swiftly and not needing to catch a breath. On Strikezone, they dominate and you don't even need to be comfortable with the weapon type to have a decent game. I think Shotguns are a good choice but the ones in Ghosts just seem too damn powerful to play against on many maps against players who are very skilled at using them.
I don't know how popular they are on the consoles but I imagine they are a good weapon of choice for many players on different modes and maps. They are just very tough to play against on PC.
