People wanting a support class. Why?

[MintnHoney]

But I want to know, what do you actually want from a support class?

There are some jobs that would currently benefit from being in such a role and the hope is that those roles, in addition to any new jobs that would enter the role, at least for me, would be able to provide their intended or projected effects without having to worry about balancing them to fit specifically within the confines of the DPS, Healer, and Tank roles.
