Jadefire Betrayers, Hellcallers, and Tricksters (marked RED on the map) - These foul Satyrs infest north-western part of Felwood. Slaying them will help Druids reclaim Felwood, and provide you with a lot of Gold. These Satyrs drop a lot of Runecloth, Felcloth (the main source of income from this spot, check the AH prices), 16 Slot Bags, Vendor Trash Items, and some Pocket Money. Satyrs can be Pickpocketed, so this spot is especially good for Rogues. Recommended Level - 52+ (54+ to be extra safe, as Satyrs can be problematic because they tend to run away on low health and pull additional enemies).
Acidmaw Bears, Grizzlies, and Maulers (marked BLUE on the map) - The once majestic Bears of Felwood are now corrupted by Fel Magic. Free them from their painful existence, and earn some Gold in the process. Felwood's Bear species drop a lot of Vendor Trash Items (Bear Jaw, Bear Flank, Savage Bear Claw, and Large Bear Bone), 14 Slot Bags, rare 16 Slot Bags, and most importantly can be Skinned for Thick Leather, Rugged Leather, Warbear Leather (used by Leatherworkers for Warbear Harness and Warbear Woolies Recipes), Thick Hide, and Rugged Hide (Skinning is recommended for this Farming Location, as it will greatly increase potential profits).
Swamp Jaguars - Western part of the Swamp of Sorrows is inhabited by deadly feline species, the Swamp Jaguar. These big cats drop a lot of Vendor Trash Items (Long Soft Tail and Bristly Whisker), Large Fangs (used in Leatherworking, Blacksmithing, and Alchemy Recipes), Wicked Claws (used in Leatherworking and Blacksmithing Recipes), 12 Slot Bags, and most importantly can be Skinned for Heavy Leather and Thick Leather (Skinning is not necessary for this spot, because of Jaguar's already great loot table). This is one of the best spots for farming your Level 40 Mount Gold. Recommended level - 35+ (you might need to clear other Swamp creatures as well, just to be safe).
The third location and the last is in the Badlands. And another Whelpling spot, this time in the north-eastern part of badlands. Home to the Scalding Whelp with levels between 41 and 43, hp between 1500 and 1700 hundred and around 1800 armor.. which makes it one of the most balanced spots to grind for exp and gold. Skinning is pretty much required here to get the most out of this spot. During the 2 levels I grinded here made around 150 gold not counting the epic drop Ardent custodian. Most of the gold came from selling heavy and thick leather, small flame sacks, the grey items and lots of greens including plate items that sell pretty decent on the auction house...
This is the lamest excuse to try and pin it on a cash grab. Tbh this is just you complaining to complain, there is no issue. If you wanted to play classic on launch you'd have to sub before hand anyways you're still paying month to month you don't pay by week. The only way you'd lose that money is if you quit before your sub ran out later on down the road.
