And that's just New Hope. Nothing really Force/lightsaber related no, but still, not really a cakewalk either. I actually don't think Rey had that many straight up fights in TFA, at least not space ones, but she did have a handful of close quarters fights that I can recall, and it's implied that she had been in several all her life just to survive.
I think the bigger issue with those who think Rey is a Mary Sue is the contrast - she's better at those around or gets to expert level instantly. Luke is a decent gunner and with a rifle. Rey is a pretty good marksman 5 minutes after Han hands her a pistol (and has to remind her not to point it at him and where the safety is). I don't know that these examples are the ones usually mentioned. From what I've seen it's "She's a better mechanic than Han" and the instant Force ability.
