As it has already been pointed out, most of those issues arose when S-E tried to "westernize" the FF series to appeal to a broader audience while ending up alienating some of their already established bases.
I don't think there's anything wrong with the RPG genre nowadays. One series following a set of misguided trends that are not easily appliable to it's spectrum shouldn't overlap other series that have done good things for the genre itself, even on this generation. Even if that series is one of the most critically succesful and popular in the genre, since if that series fall, others will come and take it's place (and I'm speaking as a FF fan myself).
