This is a guide made specifically for rogues and will help out your leveling tremendously.

It also will give you great places to grind as well as make you tons of extra gold while power leveling to level 70.

First things first, here is a list of items that you will find very useful while grinding and will help reduce cooldown time between fights as well as helping you dish out the most DPS you can while grinding:

1. Frost Oil x 4
2. Instant Poison x 20
3. Thistle Tea x 5 – helps a lot whenever you are in trouble because it will help you kill things quicker. Great to use whenever you are fighting 2 mobs at the same time.
4. Soothing Turtle Bisque x 20 – This gives you +8 Stamina (80 more life) and +8 Spirit, nuff said.
5. Bandages x 20 – You can probably figure this out.
6. Healing Potion x 5 – Same goes with these.

Next thing we need to analyze is what spec you want to use when grinding. Just remember this really is just a base as you should see what you would rather use that would fit your playstyle better:

Assassination
2 points in Remorseless Attacks
5 points in Malice

Combat
5 points in Lightning Reflexes
2 points in Sinister Strike
3 points in Backstab
4 points in Dagger/Dual Wield Specialization

Next thing we want to focus on is equipment that you can use at level 30. I'm not going to tell you which equipment you must have as long as you remember you want to have high DPS and a good crit chance. Any equipment that helps out that bottom line would be good to use.

Now we are off to the different grinding spots!

30-34 – You have a couple of different choices here. Vul'Gor Ogre Mound in Duskwood (west of the road leading to STV), you could also grind on the Tigers and Panthers while doing the mastery quests from Nesingwary's Camp in STV (of course, you might want to avoid this area if you are on a PvP server as you will more than likely be ganked a lot.), Last but not least there is Dustwallow Marsh which might be a little bit safer than STV, you can grind on the tons of animals there and also get tons of leather from skinning.

34-36 – Stanglethorn Vale at Lake Nazferiti, you can grind on the Venture Co. Geologists and Mechanics. They tend to drop a decent amount of silver per kill (around 2-3) as well as green drops.

36-39 – Arathi Highlands you can grind out your heart's content at the different Elemental binding areas. They tend to drop great cash and some items that sell on the AH pretty well. Only downside to this is the elementals are immune to poison so DPS might be down a little bit. On some servers these areas are camped 24/7 so you really want to see if there are people there already before getting started.

38-42 – Another great place you can grind is Badlands. There are tons of animals everywhere which you can quickly kill and skin. Just make sure you have tons of room in your bags for all the vendor trash you pick up.

39-44 – Tanaris just south of Steamwheedle Port is a beach that is covered in turtles which you can grind on and skin. You can make an extra 15g an hour while grinding these. Every little bit helps! :)
