BRDs already compete with other roles. While they operate at a lower sustained DPS level, they remain almost unaffected by mechanics in battles that lead to off time for other DPS. Shortly, they have the most on-target time. For many fights, this can lead to them being highly competitive if not top.

Like any other DPS job, though, there are also fights where BRDs arent particularly good: fighrs where there aren't very many mechanics that force offtime for melee or movement for BLMs. Eve then, BRDs are desired for their songs as a recovery tool.
