I would suggest Kicks Profiles which are the only thing I used to level, but as you want a AFK I would recommend ArcheologyBuddy, that's what people says that would let you be the most time AFK, although it can get stuck and need a little babysitting.
Good luck in your up, and do it fast since on Aug 28th a new patch that will change everything will be deployed and HB Dev Team will need some time to get it in shape
If you aren't geared then use BGbuddy, DungeonBuddy or ArchaeologyBuddy.
Undergeared rogues suck at questing and grinding. But if you are good geared then use Kickz questing profiles.
