Onyxia's Deep Breath attack has been the downfall of many an attempt on the Brood Mother's lair. As guilds put in more time and more attempts towards downing the great dragon, some noticeable patterns emerged. Every one of the following factors have been empirically proven to affect the frequency of Onyxia's Deep Breath:
What Causes Onyxia to Deep Breath More?
Not enough DPS
Not enough DOTs
The group's Raid ID
The race of the raid leader
The race of the main tank
The class of the raid leader
The class of the main tank
The tone of voice of the raid leader, and whether or not he has techno music playing in the background.
Not all odd groups are on the left and/or not all even groups are on the right.
People are not DPSing very, very slowly (and by slowly, I mean f#@%ing slow).
Someone got kicked/feared into the whelps (for not being where the f#%@ they were supposed to be).
The players in the center are standing next to other people.
The real-life gender or race of the raid leader or main tank
Whether Onyxia's head is currently on display outside of Orgrimmar/Stormwind
Whether anyone in your raid has downed Drakkisath within the past 24 hours
