Leveling a Hunter in the beginning can be a bit more challenging than most.
You reach level 12, do the hunter training quests to tame your new pet, and what's this?
"I have to get food and my pet isn't happy?"
No worries. Hunters are now able to train pets at level 1. Taming your new pet will be easier now with the new happiness system. Feeding your pet will now only restore the pets health after combat, and the happiness level will always remain at happy. That also includes pet death in combat regardless of Questing, Instances, Battlegrounds, and/or Arenas.
Threat is now a bit easier to manage for those new pets... Now hunters can enjoy those attacks within range.
