What are you doing to constantly be in position to get shotgunned? I played Comp basically solid yesterday: I think I died maybe 4 or 5 times to shotguns. And this was while using the Ikelos hand cannon, meaning the range was putting me in much greater danger of being close to the kill-range of the most popular shotguns. It's all about movement and positioning. Once you fix that, shotguns become a minor annoyance, and the apes will hand you kills left and right. See white light: kill them before they ever ADS. Biggest issue, stop hanging out near choke points. I know it's natural cover, but it's also a good place to slide-shot. Find a piece of cover that you can move to obscure the sight line without being pressed up against. That way if a shotgunner tries to rush you, they are in the open the whole way; no free approaches. Back up while hitting your shots, and most of the time, their body won't even reach you when it finishes falling. And don't rush so much. Getting out of position is food for apes. I could go on and on, but there are tons of videos out that explain all this and more much better than I could. Shotguns are fine, you just have to know how to play against them, as opposed to playing into them.
