Though I suggest doing some quests along the way, the fastest way to get to level 60 by far, is just sitting down and grinding your way through. After about level 35, quests make you walk all over for rare drops; really not worth it in most cases. Once you hit 50, you’ll run across some very long linked quests that need you to visit high-level instances for some nice gear. Of all the classes, only the mage comes close to the rogue in grinding speed. Other classes need to take quests because grinding isn’t as fast. That being said, quests in Ungoro are worth it since you need to grind off the creatures anyhow - 2 birds with one stone. Though grinding is by far the fastest way to get to 60, it is also the most boring and anti-social. Thanfully, once you hit 60, there’s very little reason to grind as quests will generally give more experience and point you in a new direction. Quests in the Outlands give between 10,000 and 20,000 experience. Considering a single kill without rested is about 500xp, you can see the advantages here.
Quests I do suggest doing are.
●All the animal mastery quests in STV(30-35). You get good leather armor rewards from these.
●Scarlet Monastery quest to kill the 4 leaders(35-40). You get a choice of a superb sword or dagger.
●Quest to kill the Thermaplugg in Gnomeregan(33-36). The Triprunner Dungarees are pants that you’ll be using for at least 15 levels after you acquire them
●Quest to kill the Princess in Mauradon(48-52). The Thrash Blade is one of the best swords in the entire game.

●All quests in Ungoro(50-52). All collection quests and you can get 2 levels from these quests alone. Just remember to bring in a Mithril Casing. Also, start the long but

important Linken’s Quest. It gives you a boomerang (trinket) that can unarm/stun opponents. With rested experience, you can get around 60,000xp/h in Ungoro.
●All single player quests in Outlands
Suggested Grinding Areas
Overall, you want to focus on humanoids (and some undead). They drop cloth that’s used for First Aid, so you can basically heal yourself indefinitely. They also give a chance to Pick Pocket a junkbox, used to increase Lock picking. Finally, they drop money and have the highest chance of dropping a cool item (green or better). As for types, you want to focus on casters who, when combined with kick and gouge, are dead before you know it. You can try humanoid ranged attackers as well since at close range they do very little damage and have low hp. If you take skinning, you can level exclusively off beasts and make money but your lock picking skill will suffer and you’ll need to buy cloth to use First Aid.
These are generally designed for only one person to grind in. If someone else is there, move to another area. There are plenty of good areas to try out as well. Just remember, Humanoid/Undead and casters are what you’re looking for. And above all things, avoid casters who have damage shields (shaman usually). They destroy rogues.
From levels 1 through 30, you’re basically stuck in your starting zones. Since there are so many, I don’t think there’s a giant need to explain that here. 1-20 is pretty simple and quick. Horde from 20-30 do Hillsbrad, Alliance does Wetlands and Duskwood. Quests are still good at this point.
30-35: Stranglethorn Vale (get all the Green Hills pages from the AH before going)
●Start the animal mastery quests and do a new tier every level
●Kurzen’s Camp (30-33)
●Venture Co. Basecamp (33-35).
35-40: Alterac Mountains/Hillsbrad Hills
●Do the Murloc and Naga quests. They are just south of Southshore. You can just kill Naga if you want too (33-35)
●Alterac Ogres. Can’t miss them. (35-40)
38-40: Stranglethorn Vale
●Jatailai Troll camp (38-40). Keep the Mojo and sell at AH.
40-42: Badlands
●Ogre compound in SW corner.

40-45: Tanaris
●Wastewater Bandits, in the north-east corner. (40-45). Keep the water satchels.
43-45: Feralas
●Naga south of Feathermoon and Isle of Dread (43-45). There’s a quest to kill them, so pick it up if you can. Gnolls are also good but they are near the Horde camp.
45-50: The Hinterlands
●Altar of Zul trolls. Kill Soothsayers. Axe Throwers if you’re getting too fast. Keep the Troll Necklaces. Keep the Wildvine and sell on AH(45-50). Best XP spot in the game in my opinion.
47-50: Azshara
●Ghosts at start of zone, or at end of road (47-50).
47-50: Tanaris
●Dunemaul Compound. Ogres are easy enough to kill but some can hit really hard. (47-50)
50-52: Ungoro Crater
●Marshall’s Refuge. Do as many of these quests as you can and you will get 2 levels off them. Really easy exp for just running around. Any quest that wants you to kill Pterrordax you should not take. Start the Linken’s Quest.
●Perfect place for skinner to grind is just East of the Refuge killing Gorillas or the SE corner killing Raptors.
50-54: Azshara
●Demon Satyrs North of ghosts and in the top North (50-54). They have minions though not tough ones.
●Blood Elves(50-52) on the North East corner. They are mostly casters but have very low hit points and no one is ever around to compete with.
50-54: Felwood
●Demons Satyrs in Felwood. Middle-west of zone (50-54)
●If you don’t have Demonslay, kill Ironwood Stompers (50-54)
54-60: Winterspring
●Ghosts on the lake. Lower central part of zone (54-56). Can easily be farmed if you have the quest called The Ruins of Kel’Theril (just don’t loot the shards you dig up) as it spawns 2 ghosts every time you mine. Easy kills. Good loot.
54-58: West Plaguelands
●Hunt Scarlets in the middle of the zone. (54-58)
●Grind for Argent Dawn faction in the fields.
56-60: East Plaguelands
●Demon Hounds across south end of zone (56-60)

●Mossflayer and Eyeless in middle of zone (56-58) and north-east (58-60). They spawn with chests.
●There are a lot of Kill X quests which you should pick up.
58-60: Burning Steppes
●Orcs around Stronghold. Takes a few tries to get used to though. Best place bar none as half are casters (58-60)
58-62 – Hellfire Peninsula
●Orcs around path of glory
●Undead south of Honor Hold
●Voidwalkers in South West
62-64 Zangarmarsh
●Bog Lords in South Caves, very low HP
●Kill the Sporebats for a nice buff
64-66 Terokkar
●Sunfury Elves in North East. Very easy kills, rings they drop sell for 1g per
●Arakkoa around the zone, feathers sell well
66-68 Nagrand
●Lost at Sunsrping Post
●Ogres just North of Halaa, Northwing Cleft. Keep the beads
68-69 Blade’s Edge
●Ethereal above Razor Ridge
69-70 Netherstorm
●Manaforges, except Ara
●Etherium Staging Grounds
69-70 Shadowmoon Valley
●Illidari Point & Legion Hold
●AVOID Ruins of Baari, currently very buggy
While going through this, make an effort to do the quests I mentioned above. In general, leave elites alone. They are simply not worth the effort involved, unless that is; you are camping for a specific drop.
