Stable Size to Increase

[Slashdance]

Senior Game Designers Josh “Aggrend” Greenfield and Aidan Moon, as well as Principal Designer Kris Zierhut, speak about increasing the Hunter pet stable. They do not define a specific increase or total number, but confirm there will be ways to increase it, then discuss that they understand that not only is a "gotta collect 'em all" kinda thing, but also necessary in order to have access to different abilities, training, and raiding.
