BRD does not need a buff or a physical vulnerabilty, because BRD is better than MCH with a 2 mages comp.
MCH is better with 2 melee comp, and BRD is better with 2 mages comp, where is the problem? should be BRD better than MCH with any comp? It's not good.

If BRD is better than MCH with 2 mages comp, BRD can't be better with 2 melee comp.
