23-26 - Duskwood - Tranquil Garden's Cemetary - Skeleton Warriors/Mages
26-32 - Duskwood - Raven Hill Cemetary - Ghouls, Skeletal Raiders, Skeletal Healers
*28-32 - One Thousand Needles - Splithoof Crag-Centaur
*33-37(?) - One Thousand Needles - Shimmering Flats - Vultures, Basilisks, Scopids, Turtles
The Skeleton Warriors and Skeleton Mages there are great. They're easy to kill and have a lot in a very compact area.The Ghouls at the Raven Hill Cemetary are GREAT. Lets not forget the skeletal raiders and healers. They're good too.*The 1k Needles and Shimmering flats have mines, drop silk, etc., etc. for horde. Unsure of how good it is. Wasn't extremely specific either.
*32-36 - Arathi Highlands - The Troll area SE area of the map
*36-40 - Badlands - basically south of the entrance from Dun Morogh ---- just avoid Uldaman entrace, as high traffic so can't always grind in peace.
*35-45 - Feralas - Area? - Grimtotems
32-36 - Stranglethorn Vale - Venture Co. Base Camp - Venture Co. Geologist, Gorillas
36-39 - Stranglethorn Vale - North of Balima Ruins - Gorillas
*38-44 - Stranglethorn Vale - Behind Arena - Raptors
39-42 - Stranglethorn Vale - Mistvale Valley - Gorillas
*40-46 - Stranglethorn Vale - Crystaline Mine - Basilisks
The Venture Co. Base Camp isnt the best, but it was good. There are also some level 33 gorillas around there that are GREAT for grinding till 36 also. They should be north of it. from 36-39 its more gorillas! Cause they're easy and go down fast! and from 39-42... well.. Gorillas are great. You'll learn to love em. nice drops too. Good for farming money. You should have about 40-70g saved up if you play it smart just from the regular drops off gorillas.*Also, with the raptors, skinning, and patience they give you good exp and money. *At the cave there will always be 4 mines + 1 chest and basilisks. With skinning and mining you can earn enough money to buy a mount in 1 day.
you need 4 large bags, recommend runecloth, they are worth the money.
*42-47 - Swamp of Sorrows - MistyReed Strand - Murlocks
42-46 - Tanaris - Waterspring Field/Noonshade Ruins - Westwander thief/bandit
*43-50 - Tanaris - Ruins - Ogres
*45-50 - Hinterlands - Everywhere - Everything *45-50 - Hinterlands - Jintha'Alor - Elites
46-48 - Tanaris - Lost Rigger Cove - Pirates
I love the westwanders because not only do they give GREAT exp and DROP fast, they also drop westwander pouches, which every 5 you get, you can turn in for a FREE 380 exp and a package that usually carries food and a SUPERIOR HEALING POTION. FOR FREE!. Takes about 10-15 kills to get 5 and every hour you can get about 1-2 stacks which gives you about 3-4k more exp per hour!*The ogres drop good items and gold and they should drop fast cause they're ogres! Also some are casters.*Swamp of sorrows is a great place for horde (atleast thats what one of these cool warriors told me).
*49-55 - Burning Steppes - Ogre cave in east just ouside the human outpost.
48-54 - Feralas - Ruins of Ravenwind - Harpies
I cant believe im telling you the harpies... This is the GREATEST spot you will EVER find to grind. They do low damage if your a warrior, drop TONS of mageweave, Drop TONS of good items, and you have a chance to get an epic every now and then. After 2 levels of farming here i got a Bloodrazor, and its mixed with caster mobs. GREAT area. I love it. You'll never run low on bandages either.*The Burning Steppes one was contributed, but its ogres, EASY kills too.
*50-56 - Azshara - Unkown Area - Blood Elves/Satyrs
*50-53 - Burning Steppes(?) - Unknown Area - ogres, caster + melee + rare spawn.
mythril + gold + thorium mines inside cave.
54-60 - Winterspring - Yeti Cave - Yetis
*54-58 - Azshara - N/A - Blood Elves
*58-60 - Winterspring - The frozen lake - ghosts
Yetis aren't the greatest place - not nearly as good as the harpies, but still a nice area and a good place to get some great items.*Burning Steppes one is more for gaining money fast, and it seems nice. Ogres are the greatest

*Bloodelves/Satyrs are great, drop runecloth and rare recipes sometimes. However its highly used on PvP servers so be careful.*More bloodelves in Azshara it seems, go there too!
*54-60 - Deadwind Pass - Ogres + Vultures.
*This is a garanteed money + runecloth drops.
Since im getting a bit lazy and this is a nice format already ill just leave it as is
*50 - 55: Felwood (Satyrs, furblogs)
Azhara ( Elves, Satyrs)
WEstren Plaguelands ( Any Undead)
Un'goro Crater ( Fire Elementals)
*55 - 60: Corrin's Crossing, EPL
Plaguewood, EPL ( Lot of thourim here.)
Tyr's Hand, EPL ( 52-57 elites )
Silithus (Air Elementals)
Winterspring (Ghosts, Yetis, Owlbeasts)
