WOW Power Leveling: Provided you have charmed a pet in pre-searing as a non-ranger primary
You cannot get WOW Power Leveling around the single pet restriction – using Echo while charming a pet will duplicate the Charm Animal skill upon completion of the first Charm Animal; however neither copy of Charm Animal on the skill bar will work to capture a pet, as there is a pet currently charmed.
It is possible to have a pet while not having Charm Animal on your skill bar.
Provided you have charmed a pet in pre-searing as a non-ranger primary, using the skill while trying the ranger skills (but not having accepted the ranger as secondary class), you can visit another trainer in an instanced area and try a new secondary (or select a secondary) – all ranger skills will disappear from your skill bar, but your pet will remain so long as you stay in the instance.
Even passing to another instanced area will cause the pet to disappear; we can conclude that the existence of a pet is checked for upon entering an instanced zone.
Other methods to have a pet without having Charm Animal on your skill bar are to replace Charm Animal when unlocking a skill in an instanced area or through the Ranger path quest in the Crystal Desert.
