"I can appreciate this display of grief from Swea of <Once> on Sunstrider-EU, particularly since death knights tend towards the emotionless side. But what did she think was going to happen? Sure, we no longer have to hold our horses in our enormous, invisible backpacks, but there's not exactly a ton of breathing room in those tiny little squares in our Pets tab. If we don't take them out enough, our mounts and minipets will inevitably turn on each other. This little guy was probably the second to be eaten, after the hawkstrider."
