I would absolutely recommend Xu-Fu. For strats against NPC pet battlers, it is the go-to resource.
Conversely, I would suggest you avoid Wowhead. It is not only a malware infested cesspool, but it is extremely slow to update information.
Small correction. Itās Mechanical Pandaren Dragonling, not Hatchling. (Easy mistake, though. So many of our pets are hatchlings.)
I would add it doesnāt hurt to double up, or even triple up, on some of the pets on this list. One of the reasons for this is because of pet dungeons, which you will eventually want to be doing.
Pet dungeons do not allow you to heal your pets. Youāre allowed to complete one dry run, where you may heal your pets in between. Once you complete that, and youāre going back for the currency to buy new pets or to take a chance on pets that are random drops, your healing in between pet battles are over.
Consequently, if something goes wrong and the RNG gods have frowned upon you, youāre stuck. Youāll have to exit the dungeon, heal your pets and start all over again from the beginning and hope for better luck.
Therefore, I would say two of the Darkmoon Tonks and Zeppelins. Three Mechanical Pandaren Dragonlings (the value of this pet cannot be overstated). At least two Iron Starlettes. I would say P/P is the best breed, but H/P is also useful for survivability. Two Ikkyās. I have three P/P Nexus Whelplings. Three Emerald Proto-Whelps. I prefer the P/P breed. Two or more Teroclaw Hatchlings.
If you want another Mechanical Pandaren Dragonling, just reply to this and let me know; Iāll come to your server and send you a free one. (One of my many, many, many glaring failings as a player is that I over-farm mats. I was tired of trying to make all this work with just one Mechanical Pandaren Dragonling, so I leveled up my Engineer to make my own. So, of course I farmed and assembled enough mats to make 42 of them.)
Frogs, rabbits, snails, foxes, skunks, and any of the other common pets that I might have overlooked. Theyāre abundant, yes, but their also supremely useful. I used to solo the end boss of Wailing Caverns pet dungeon with Yellow-Bellied Bullfrog. It took awhile but he mopped the floor with the boss and both his backup pets.
I frog-kissed that final boss so many times, Iām surprised he didnāt ask me out on a date.
Rabbits, with their ability to avoid attacks with Dodge and Burrow, plus their innate critter bonus, makes them the absolute bane of Undead.
Snails are essentially giant bags of health, and with the diving attack, theyāre great against Elementals, which you will see a ton of in the Gnomeregan pet dungeon.
