I'm trying to help a friend start pet battling...from the ground up.
When he speaks to the battle master (Elwynn Forest, Westfall, STV) to start the battle his heirloom tab pops up.
Had him turn off his addons and try again...this time he accepts the quest then cannot speak to the tamer any further.
Google has returned no helpful information on this matter.
He used the garrison stone to level his first 25 pet now I'm just trying to run him through leveling a few more pets to get the hang of things/start on Pandaria bosses ect
