In my experience, priests are one of the rarest classes in the game, in general... something that seems to be supported by stuff like wowcensus data. Furthermore, they seem to be even more rare than the numbers indicate they should be, based on battleground makeup, though they are one of the more common Gladiator classes. And finally, their section of the MMO forums has the fewest posts.
And, the posts I DO see in here are about shadow this, shadow that, shadow compared to ret pallies or frost mages for mana regen, etc.
When people are sitting at 80, starting to raid top end content, am I going to be the only healing priest left? I hope so
