Now that I can carry around all my pets and mounts all the time, I needed to find a better way to summon them than stopping to scroll through 5 pages of them every team I wanted to have one out. I ended up using macros and posting them to my right hand bar. Here are the ones I am using:
/run CallCompanion("CRITTER", random(GetNumCompanions("CRITTER")))
/run CallCompanion("MOUNT", random(GetNumCompanions("MOUNT")))
It's nice to use macros for things more fun than tossing tainted cores at raid members or pleading to have someone click the spine off me so I can continue healing kthxbai.
