These beasts are not out in the open for all to see; instead, they are hidden away. Hunters will have to track the beasts via sets of mysterious tracks found on the ground, rather than the usual tracking methods. These tracks are apparently only viewable by hunters; other classes can not see them. If you follow the tracks to their natural end, you'll see absolutely nothing at all. But if you cast a flare, you'll find a rare pet of your dreams just waiting for you to tame it.
This is not only a fun mechanic, but it also prevents random players from wandering around indiscriminately killing the rare pets that hunters crave. And the creatures themselves seem to be elites, which discourages other players from intervening on a hunter's tame as well. Players killing rare spawn spirit beasts and other creatures has been a source of irritation for many a hunter over the years. Perhaps this solution will keep the creatures in the hands of those who can use them for more than padding their pocketbook.
