I also saw another thread on a different realm forum where the OP kept a list of the top collectors for both mounts and pets for the realm. I thought this would also be an interesting idea, especially now that you can check out someone's statistics (and therefore number of mounts and pets) through the armory! Just post on your collector with the number of mounts or pets you have and once its verified by the armory I will add you to the list. Feel free to talk about all things mounts and pets as well! I'll keep a list of the top 10 collectors for both mounts and mini pets on the realm, as well as keep this a thread for sharing and discussing.
Remember, collections are counted on individual characters, not a combination. :)
