I prefer BRD to be subbing WHM so the WHM is free to handle other duties aside from status debuffs. Erase has a longer timer as well and doesn't cross parties, so that is necessary in a lot of situations. The only exception would be BLM/BRD for ES, which right now isn't a necessity but I'm sure will be again in the future.
Edit: Also I'm not sure what BRDs you play with but 9mp/tick is pretty lol.
