Family Battler of Eastern Kingdoms

Each trainer can only be battled once per day, so this achievement takes a minimum of 10 days to complete. This must be done on an Alliance character, being in a raid group will not work, and you cannot abandon the quest after completion.

For the Beast family battles, use Infernal Pyreclaw P/B with Adrenaline Rush, Cleave, and Great Sting; Zandalari Anklerender P/S with Bite, Primal Cry, and Black Claw; and a Tarachnid Stalker or any Spider S/S with Strike, Brittle Webbing, and Spiderling Swarm. Keep Great Sting active as much as possible, spam Cleave, and use the Spider to absorb high-damage two-round abilities such as Fly, Burrow, and Dragon Breath by combining Brittle Webbing with Spiderling Swarm.

For the Critter family battles, use Damp Skrat B/B with Barbed Stinger, Nibble, and Great Sting; Lovebird Hatchling S/S with Alpha Strike, Lovestruck, and Pheromones; and Perky Pug P/S with Bite, Buried Treasure, and Trample. Open with Great Sting, then swap to Lovebird to apply Pheromones and keep both DoTs active. When facing Major Payne, lead with Lovebird instead, use Pheromones first, then immediately stun, keeping the enemy Bear pet in the backline as long as possible.
