I've started using them recently and they definitely require more aim and strategy than any other gun in this game. Constantly see people on here complaining about them being EZ mode, but if they were so easy wouldn't everyone run them? All anyone ever uses is the hellriegel on console and automatico on PC which shows what the easy weapons truly are.
If you miss with it you're pretty much a goner. It's the only weapon where you constantly need to position yourself properly and plan out your engagements. I'm talking about the pump actions shotties here just so we're clear.
