On topic: homogenization, while has its obvious cons, is more of a good thing overall. Yoshida did say before 5.0 release that they're trying to get rid of strict meta mentality, and in order to do so all jobs within a role need to perform on a more or less same level. Yes, it kind of makes job choice a matter of aesthetic rather than utility, but it also gives people an opportunity to play jobs they visually like without being left out from doing content just because meta lovers won't invite them into parties. All jobs still have its identity, it just changed its form of presentation a bit.
