Haha, yea my wife's been telling me the same thing
I don't agree on the SMG comment at all, as there's not a single map I can think of that you can't dominate on with either the Spitfire, Cordite or MX9. You do need to adjust your playstyle to suit the gun you use for sure, but I tend to run SMG 80% of the time. The spitfire is basically a god gun, that deletes people at close range, and has such as predictable recoil, you hit shots from across the map if you burst it. Same applies to the others, the Spitfire's just my current go-to if I want to be guaranteed a good game.
