I haven't bothered to get a good look at Cia, yet. I don't have a Wii U and don't specifically plan to get one, so I somewhat ignore "those games I cannot get, until I get the system for them." Hyrule Warriors interests me, but I'm more into my 3DS right now...
Eh. The girls from Soul Calibur always bothered me because they aren't really built to fight. I've seen some comics along those lines - Ivy and others going "Oh, the back-pain!" I think programmers and designers for games ought to study actual females, female athletes and the like. I know it's all fantasy, but there are certain things that being "top-heavy" and certain clothing make more difficult. It's not about not "showing off one's assets," it's having unrealistic assets. Then again, overly-muscled men bother me, too. I understand strength, but after a certain degree of bodybuilding, things start getting ugly. I've also heard that some bodybuilders who do it for the contests and cosmetics actually have some problems with rigidity - as in, there is a point where a strong man is so muscular he cannot actually fight.
Being playful with sexualized things doesn't bother me too much in games or fiction in general. I mean, the innuendo in Ocarina of Time and Skyward Sword is *hilarious.* I also like how, as mentioned, Nintendo plays with the Fan Disservice, as well - that is, "fanservice" type things applied to things no pervy young fan wants them applied to - such as fat, naked bathing Headmasters and Moblin-jiggles!
It's just, there is a point at which one has to worry about characters getting objectified - but you can't listen to everyone's complaints about games you like because some people have little sense of humor.
