Advice in picking a main for a returning player

[Aebel]

Hey everyone, returning player here. Played a little at the launch of ShB but life got busy, but I'm back. I used to like playing support jobs like BRD or MCH, but I know both of them gradually lost their support abilities until DNC basically replaced both of them. I have several classes in the 60-70 range (and several lower I wouldnt be against leveling) and I'd just like some advice on which I should play.

Basically I prefer to play a supporting role in the game, I don't mind tanking or healing but I would prefer my first character at 80 to be a dps just so I'm not as relied upon by parties as I'm learning the new content. I have it narrowed down to SMN, NIN, DNC (I know SMN isnt that support heavy) and I'm wondering what I can expect to experience playing these classes now that ShB has been out for a while and 5.1 releases some (what looks like to me) big changes to classes.

Thanks in advance!

Edit: Changed SB to ShB where applicable.
