I queued up for PotD a few weeks ago as SCH and was grouped up with 2 tanks and a level 45 WHM. 3 floors in the WHM says shes just going to heal, but we had very little damage incoming and the fairy was covering it just fine.
So... I suggest she use this place to practice DPSing as it's not really healing intensive. All I get back in response - "Why should I DPS? THAT'S YOUR JOB."
