I have just tested out a carrion bird in a raid and i would say its really good and wonder why there is like no hunters using one. It does great dps and has a nice AP reduction skill.
Demoralizing Screech
Blasts a single enemy for 84 to 129 damage and lowers the melee attack power of all enemies in melee range by 574. Effect lasts 10 sec.
The ap reduction is equal to a fully talented warrior shout or druid roar which none of them usally dont spend points in. Pallys vindication is the only thing that can compare and even so im not sure if they stack or not since both debuffs can be on the same target at the same time.
So why are they so unattractive when they can bring a nice debuff?
