I know a few people who would have wanted to "main" BLU. I feel that, despite being able to play every job in this game on one character, there is still a palpable sense of identification and ownership with one's favorite job. Friend of mine has been a SMN since 2.0. She's played other jobs and enjoyed the content with them, but she keeps going back to SMN. I think it's a shame this kind of "this job is the one for me" feeling is lost when the job is barred from functioning like a regular job.
