Acrophobia, for those who don't know, being an irrational fear of heights. Does anyone with that condition have it come into play during the Spine of Deathwing fight?
Personally, while I'm not acrophobic, I find even myself getting a tad cautious during the fight. A little part of me is afraid that I'm going to walk over the edge by accident, especially when we're forcing Deathwing to barrel roll and stacking on one of the corruption wounds. It got me thinking earlier how people with the actual condition might handle it. After all, you're fighting on the back of an angry dragon hundreds of feet over the ocean.
This certainly wouldn't be the first time a phobia might come into play during a boss fight, particularly people with arachnophobia trying to do quests involving spiders or having tried to kill Maexxna when Naxx was current content.
