BRD does have the lowest DPS of all DPS classes (as of 3.2 IIRC MCH passed it) but BRD utility is always appreciated when it fits with the other members of the team.
E.g. Have a BLM or SMN as a ranged DPS, or a DPS Healer? Foe's Requiem
Have an AST or WHM with intense healing needs / death recoveries? Mage's Ballad
Have a DRG on the team, BRD dps is increased.
Have PLD tank and no NIN on the team? Army's Paeon because that PLD will be out of TP after about 5 minutes without a break.
Have WAR tank using Berserk? pre-cast Warden's Paean, saves the healer from Esuna / Leeches / Exalted Detriment.
