Assistance from a rogue leveling guide
There are many people that will tell you you don’t need help while leveling, and that you can do it on your own without any outside assistance or any add-on’s or mods available for the game. Don’t listen to them, get a Rogue Leveling Guide. These guides will help you by showing you things about the class that you probably don’t know, and won’t learn unless someone tells you. For example, did you know that you need a slower weapon in your main hand in order for sinister strike to do more damage? Or what about this: leveling as combat is the best spec for a rogue.
