To be blunt: As a healer I don't give a damn about content that I can't play as a healer.
No, going in and playing a 3 button WHM-DPS is neither the answer nor fun.

There is a reason why I play White Mage and not Black Mage, I am sure you can understand that I don't necessarily find content fun that excludes my chosen playstyle, even if this MMO is far more forgiving in that regard because one character can be all classes.
