I have a Lvl 27 warlock as well, and to be honest grinding gear and crucible okay did get boring for me, I know you have no interest in doing all the replay and what not, but I decided to build a new class. I built a titan defender, 13 hrs later I'm at 22 and still having a ton of fun. Especially online. There's is nothing better then throwing my shield up and waiting with a shotgun, picking off the noobs that think they can take me in it.
