As a priest, I would really appreciate an addon which either played a sound or showed an on-screen word or something to tell me when it would or wouldn't be a good time to cast my PBAE fear.
This would operate depending what stance the warrior who is attacking me is in. If he's in berserker stance, I want a big alert saying NO FEAR. As soon as he switches out of Berserker, I need it to say FEAR and play a sound, if possible.
Thanks for your help, I hope there's someone who doesn't play warrior who will help me!
The Warrior stances are not a buff/debuff, so I dont think there is any way to check what stance they are in except by parsing the combat log messages. This wouldn't do you much good in your scenario because they may / may not be in Zerk stance when you enter combat with them. Also...zerker rage is not the only Fear break a warrior has. A Fury warrior with 10 rage can also cast Death Wish to break fear. In other words...I don't think there is a way to reliably do what you want it to do.
