Could use help picking between Drg, Smn, Dnc, and Rdm

[ItMe]

between Drg, Smn, Dnc, and Rdm. Basically I'm wanting a dps that is supportive, typically desired/valued/wanted, and somewhat easy to play or at least forgiving when having messed up, or something that is fluid enough that I can easily just go through the flow of it while paying attention to mechanics.

DNC and RDM has lots of support.
DRG and SMN have a token skill or two.

DNC is always in demand.
RDMs were being straight up turned away when people were recruiting for Alexander (Ultimate), and when my friend brings one to a raid people sometimes ask if he plays any other casters.

Honestly though, you'll probably end up at least trying out most of those lol, so just have fun.
