You seem very determined to make this a big issue lol, it's really not that bad if a BRD comes out slightly on top is what I'm saying. SE have most likely balanced it so that BRD makes up its DPS early in the fight to allow for songs to be cast and to prevent people complaining about lack of DPS from a job that stems from a DPS class. Most likely there will be content released that will require a BRD to reliably clear the content in the future.

As a tank I would much rather a healer had enough MP to heal me comfortably than a jumped up BRD who cares more about big numbers than whether the party will wipe. I agree there is content where you do not need songs at the moment, but bear in mind that these are still early days and not every job has to be used to its fullest. Even without using songs, I don't really see where the issue is here because the difference between classes is very minimal and depends on circumstance. The balancing in this game is a hell of a lot better than most MMO's and could be a lot worse.
