OP you already said that your BRDs, geared as they are, are not top DPS which means you are using them for the utility of song correct? If not you would be playing the top DPS classes which I am assuming is DRG. The reason so many of us are saying to not worry about it is because will your group honestly cut out that utility when you are already not top DPS? I doubt it so there is really no reason for your worry cause you will still be needed to sing. ^^
