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.
Plaguebats (marked BLUE on the map) - These Plague-affected beastly flying creatures roam southern parts of the Eastern Plaguelands. Slaying them will provide you with a lot of Vendor Trash Items (Evil Bat Eye, Bat Ear, Sleek Bat Pelt, and Large Bat Fang), Wicked Claws (used in Leatherworking and Blacksmithing Recipes), and maybe some 16 Slot Bags. Bats can also be Skinned for Rugged Leather, Thick Leather, Thick Hide, and Rugged Hide, so Skinning Profession is recommended for this Spot. Plague Bats have access to the Terrifying Screech Ability, so they can get annoying at times, especially for melee Classes, but are a great source of Gold nevertheless. Recommended Level - 53+.
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...
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).
Whelgar's Excavation Site - This Dwarven excavation site was overrun by Raptors (Mottled Scythemaws and Mottled Razormaws). These reptiles are a great source of Medium Leather (you should have Skinning Profession if you want to farm here, as a very large portion of income that comes from this spot is acquired by Skinning Raptors). They also drop some Vendor Trash Items and Raptor Eggs (these are convenient, as a Cooking Recipe for them comes from a Quest that is located just above the Site) that can be used for Leveling up Cooking Skill. However, the best part about this spot is that both Raptor types present here drop level 19 Twink Gear (Feet of the Lynx, Sentry Cloak, Redbeard Crest, and Twisted Chanter's Staff) that will achieve astronomical prices at the later stages of the Game (drop rates are very low, so some RNG is involved, sadly). Recommended Level - 25+.
