Arena Tournament, or "No New Pet"

"While it would be cool to provide a new pet, we're not necessarily trying to encourage as many people as possible to pay $20 and sign up for this tournament ultimately because they want a new pet. It's a nice perk to encourage people, but we don't want the Arena Tournament to be a more complicated version of the Pet Store. We want players who are serious about competing to sign up for the tournament, not just a reason to take in more money through offering a new vanity pet with each new tournament." (Source)

I heartily approve.
