Well, firstly, what women find attractive in men is not what men think women find attractive in men. Hypermuscled men are a male power fantasy, while sexeh strippah ladiez are a male sexual fantasy.
Tell this to Chris Hemsworth or Chris Evans fangirls =P
Tom Hiddleston would instead be an example of the skinny body type having a lot of market with women.
I do agree that there's a plain dyscrasy in what women want and what men perceive as being wanted by women, but I wouldn't say that muscled men are ruled out. Citing the link you provided, it is true that Hugh Jackman bulging-veined is a sight liked by men, while a women's magazine had him rather donning a sweater and smiling, but that doesn't mean that no woman likes muscles.
I think that the skinny, "feminine" type of guy a la Loki is actually more popular nowadays (especially in eastern countries), but this doesn't invalidate the fact that male characters in League have primarily two body types, muscled and skinny, and that male bodies are being objectified in advertisement just as female ones. We could argue all day whether advertisers are doing it right by understanding what women want or are just enforcing their stereotypes on society, but anyway we end at the same point: if women actually like what advertisers do, they'll keep doing it and there will be a positive feedback which will amplify the effect, if they don't and advertisers keep enforcing stereotypes there's the serious possibility for those stereotypes to be forced to become true and we're back to case A.
I read an article some time ago explaining of a certain beer brand in the USA which through marketing imposed the view that beer should be drunk ice cold and that their beer was better because served that way. Their beer wasn't superior in taste, but serving it ice cold masks the taste and people were led into thinking ice cold is the way to drink beer and that other beers were worse because they drank them at a superior temperature, which didn't mask the taste. It doesn't matter that the other brand probably tastes worse at the same temperature, because they're the ones serving it ice-cold. You can find it here, just ctrl+f for the beer part. I'd suggest reading it all though, it's about marketing and gender in gaming.
League doesn't really have anything I'd class as a pure female power fantasy, since nearly all female champions are portrayed as being within the realm of conventionally attractive in face and body type.
And no, skimpy clothing isn't "empowering".
First and foremost, I agree with the latter phrase. On the part of no female power types being there I'm less sure, because I don't have a deep knowledge of the subject. I'd dare say though that Vi could be regarded as a female power fantasy, even if a really primitive one. It appeals to certain subcultures more than to others, but I'd take her as an example of a well-made character even from a girl's POV. I'm ready to be proven wrong, but she's a strong not-skympy female character which I feel has a place in a female power fantasy discussion.
The same goes for Leona, imho, and Diana.
Obviously I'm referring to the base skins and models, since skins can range from funny to nonsense to intentionally sexy.
