Set your premade filter to include Oceanic and other foreign realms, if you haven't done it before.
And it's true that it's worth to check another garrison groups when there is no dedicated one -- not all players think about pet battlers or ever know who the tamer is while creating a group.
I don't know if it's different for US realms and between the factions, but in the Europe, Erris likes to accompany mats traders (but this is still not 100% chance).
I wait for a first post or comment saying directly "bring back MoP" in the context of pet content.
Unless there's already one, I'd like to see it.
