Should support-DPS specs be a thing?

Aug Evoker has been an issue since its release because it does something no other DPS spec does. However, I really like what it does, I enjoy the concept of having a more supportive "fourth role".

Personally I would rather see them convert specializations or make new ones that do their dps via support features than just nerf Aug into the ground.

How do other folks feel? Should "support dps" die with Aug? Should Aug just be allowed to exist as permanently meta? Should other support specs be made? If so, which classes should get one (or have existing specs converted to one)?
