I checked back a few pages and saw no threads on this issue, so I hope I'm not bringing up something that has already been discussed.
In the past week or so (or maybe since 5.4 came out, I really can't be sure) I am having quite a few issues with my pet NOT growling when the Growl spell is set to auto cast and when my pet does not have aggro on the target. I have put my pet in Assist, Defensive and Passive to test if it would activate in any of those stances when it was not working for me, and I also turn off the auto cast and back on many times, dismissed my pet and re-summoned..... but still, the growl would NOT go off. I've had to manually hit it so very often recently.
I do keep my pet on Passive most of the times due to raiding, but then I turn on Assist and auto-growl for outside of raids and this SEEMS like when I have the most issue with this subject.
Also to note: After a few hours of Growl not auto casting as it should have been, all of a sudden I just noticed that it was. I hadn't changed anything.
Has anyone else been noticing similar events with their pets?
