A few years ago, creative Hunters found a way to tame the Ancient Grimtotem Spirit Guide that was summoned by the Grimtotem Spirit-Shifters in Dustwallow Marsh. This involved using a meta gem, haste potions, Heroism/Bloodlust, and mind control by a Priest (in order to time the release of the wolves). Because of their ingenuity, Blizzard said they would allow Hunters to continue taming the Grimtotem wolves (which were classified as “wolves” upon taming, not spirit beasts). Later, they hotfixed it so they could no longer be tamed because the appearance of the wolf did not fit with the overall feel of the Hunter class. Those that had already tamed a Grimtotem wolf got to keep it, but the rest of the Hunters who had hoped to get one were unable to do so.
