Songs first: is there any way to tell if people get the crit buff when you use songs? I don't know anything buff icon that tells me they're working (other than my job gauge.) And what, exactly, does 'Repertoire Effect' mean? Am I supposed to be using a Repertoire spell in concert with the songs to get this Repertoire Effect thingy?

Foe Req: I've noticed when I'm in raid alliances that none of the other bard ever use foe req. Even in raids with a lot of bards (like 5 of us.) Am I doing anything wrong by using this spell? Is it just useless? =/ Am I supposed to be spending my MP in another way? xD What do they know that I'm just not catching on to?
