I also have glyph of stampede , but today all of them cat growl again whenever I use stampede.
I was yelled at by the tank PET TAUNT. I told him , it is only that particular spell but my pet growl is off. So I avoid using that spell except for during boss fight (or when boss near dying).
Is there anything else that can be done? My spell book grow is off by default. Am I missing anything?
