i know this is an old thread, but it can yet live!
for you have all stumbled past an excellent priest name without recognizing it...and that name is...Confess!
i have like 9 undead priests named Confess...on different servers of course, but i'm a lunatic. they are various levels, only one at 60. originally the idea was to be a shadow priest, doing the face-melt thing...but in the 40s i got bored with shadow...melting faces is way too easy. so i did a Tri-Spec through the mid 50s, which was a lot of fun, then i got serious and went disc/holy with a PI smite build. much more challenging and a lot more fun. great healing, and decent dps...i can still waste a shadow priest that doesn't know how to play, and go down fighting against a shadow priest in Tier 3 that wants to melt my face off.
i abandoned a 43 shammy to level a mage to 60, and then i abandoned the mage to level a priest to 60...bottom line = priests are a very fun class, whether you want to deal out the hurt, or help your friends. i salute ye priests! (even the shadow ones.)
take care all, and enjoy the new talents! if only they had gone with "Holy Form!"
