Class to roll?

[Staves]

I'm considering joining this bracket again after a MASSIVE break. However, I have no idea which class to roll...
I was thinking enhancement shaman, are they viable anymore? That was what my old 39 was and I'd love to re-roll him.
I'm up for any suggestions.
Does faction matter? Is there a side that desperately needs numbers? I'm Alliance generally, but wouldn't mind making a hordie.

Thanks.
