I manhandle all but Undead Rogues, who have that Will of the Forsaken ability. Fight usually goes like this:
1) Rogue pops me, does a lot of damage or cheap shots me.
2) Throw up PW:S (they can't kick me to stop it)
3) Hit SW

.
3) Renew yourself.
4) Hit Psychic Scream.
5) Now this is where the fun begins-immediately mind blast them (this is your first casted spell).
6) Depending on health, flash heal at this point if need be, else, target player and hit mind flay.
7) At this point fear is about to wear off and the player is going to be coming at you. Immediately turn away from them and running so they can only catch you when they use sprint. Usually takes them a few seconds to figure out, and in that time, you can refresh your SW

(since it does NOT require LOS to use) and renew. SW

kiting is an essential and very powerful tool in the priest arsenal.
8) Turn and hit mind blast when the cooldown has expired.
Now the rogue should be very close to death, and you've got a couple things going for you-your PW:S timer is probably back up, psychic scream isn't too long until it comes back up because of the time you bought DoT-kiting. You can fear them off again if needed and mindblast/mind flay, or go back to kiting them if they get all fancy in their pantsy with a potion or what not. Either way, the name of the game is keeping them away from you while you do your damage, which you have the tools to do.
