I can only speak for myself, but personally, while I wanted to unlock Bozja, doing it unsync wasn't an option for me because there is the element of experiencing the raids for the first time, I wouldn't have wanted to have my first experience with T.G. Cid ruined to "just get it over with", hell, I went out of my way, and played FFT before doing Return to Ivalice just to have the best possible experience with the raid series, which was, in my opinion, completely worth it.
