Imagine a 5x screech debuff........ I also like the idea of keeping a wolf on one hunter for the furious howl and keep that one on stay to keep the buff in range.

With stuff dying so fast, do you even put growl on the cast bar? You could leave it off the pet cast bar and only leave bite, claw or whatever for max focus use.

You could leave one hunter marks so you can have trueshot for them all.
