Yup, here it is... from an old Queue, I'll repost it here... not that anyone really will care one way or another...

What is the Priest's role in the world and in the game specifically? Are there plans to better formalize or change it?

As it is now, priests seem to suffer form a lack of real purpose in the world. Paladins are supplanting priests as the primary holy healers in battle (as was their original purpose, admittedly), and Warlocks and Death Knights are designed around the shadow spells and diseases that Shadow Priests seem to dabble in. This leaves damage mitigation as the sole unique role for priests to play in the world, as there are few instances of church business or outreach to which priests would be well suited.

It is, perhaps, more confusing as priests are the only class to have an armored analogue that can replicate every traditional power of the priest (healing, resurrection, and actually have a much wider selection of buffs) but has much greater combat utility and survivability (for example, there is no Gishy, armored spell slinger that can blast as well as a mage, and I suspect that creating such a class would cause an uproar).

As the Paladin has moved from a holy warrior that could sometimes focus his faith to heal to a primary battlefield healer, and the Death Knight has been given powers that actually appear to be Shadow Priest powers to any outside observer, there is less and less reason for the Priest to ever venture outside of their cloisters, and it becomes more difficult to explain their continued existence at all. Perhaps it's time to relegate them to an NPC only class, like merchants and trainers, and allow damage mitigation to be the pervue of the Protection Paladin.

Please don't take this as a complaint, I love my Priest, the character class simply seems superfluous at this point...
