I find that it's exactly the opposite, even I would do it. If I find a guy that says he plays games, the only thing I'll ask is what games he plays so that maybe we can play together. If a girls says the same thing, the first thing I'd ask if it was Wii/RB/GH out of skepticism.
That's the entire point, MLG is about skill and strategy. Shotguns kills are easy kills.
