I would only like to see the implementation of a support role, if and only if, it can be interchangeable with another DPS. Support is yet another specialize task (alongside Tank and Healer) that does not attract a ton of players and as such, just like it did in XI, would increase queue times dramatically. I'm not sure they could balance it to the point where a DPS and a Support could be interchangeable without reworking most of the other classes/jobs as well. They were nice in XI, but waiting for hours for one to log on was hell.
