I won't pretend to be a BRD expert, but if you can manage to always be attacking, keeping DoTs up without excessive clipping, making use of Bloodletter procs, and knowing when (and for how long) to use songs without party members needing to beg for them, all while taking care of mechanics, your overall performance should be fine.
BRD may not put out the big, sexy numbers of DRG or BLM, for example, but being able to run around plinking, even facing the target for a split second to activate an ability and keep running for your life from a mechanic, is a pretty nice advantage in some fights.
