They aren't going to give you better dps potential just because you have a crew of sweats that can dance around mechanic in fight X.

You have a ton of tools as a healer it's just that your group doesn't need them anymore most of the time for encounter X. That has been the curse of healers in every prog guild, in every mmo, I have ever been a part of. Healers are critically needed for encounters until said encounter reaches farm status.
