I'm level 21 atm, but cause I did most of my levelling with bounties and crucible I'm way behind on the story, which is actually cool because Nicolas, Fonzie and I have been able to run through them at the same time even though they're a couple of levels below me. Other than that I'm just grinding to try and get my crucible and vanguard ranks up, and I'll be starting to level up my second Warlock sub-class soon.
Also really keen to start tackling the level 18+ strike playlists with people I know, they're hard as hell but I'd feel so accomplished after beating one. We'll have to start getting some groups together to do that I reckon.
