Ok i read what you wanted and i can guarentee you will enjoy this build if you enjoy raiding alltho ifyou dont like healing then quite reading now. When blizzard made the priest they gave him healing shadow and Discipline every priest i know is either an imba damage melting faces guy or a healbot but me on the otherhand ? i can do as much if not more damage than a shadow priest + be accepted in all the major guilds ( as long as they need healers but what guild doesnt

). Id advise you to go shadow to level up with soon as u hit 58-60 respecc.
If you hadnt guessed allready this build is for Discipline priests heres the pros and cons.
Pros
You can heal as well as a holy priest and every 3 mins better than a holy priest ( power infusion + inner focus can get 4k greater heals at 0% mana cost ).
Pvp Is somthing most people enjoy , with this build you wont be a dps machine but you wont be a free honor kill like a resto druid / holy priest my highest crit is 1.7k on a holy fire not brilliant but not crap.
Guild. When you level this priest to 60 the first thing u want to do is look for a guild ( raiding guild )i got to level 60 within 3 days i was in molten core

.
Instances. How many times a day do you hear LFG UBRS need healer! last spot Strat need healer , ( and my personal favirote ) Paying $$$ for a healer to "insert instance here" with a priest you can get groups so easily , so easy in fact youll make a macro saying sry im not doing any instances. ( trust me
Cons.
This build isnt a pvp specific build alltho the points in shadow will help when you come up against a tier 2.5 warrior with ashkandi you will get your butt handed to you.
Race. Some alleicne guilds will not except you if your not a dwarf priest this is quite unfair imo as dwarfs racial "fear ward" is too overpowerd and it makes humans / nightelfs look like 2nd class priests. Tho if your going to go Dwarf you have nothing to fear
leveling. Basically dont use this spec to level it could be used but i tihnk shadow is better for leveling.
Farming. With this build farming can be easy and hard if you pull 1-2 mobs youll be opk any more and it gets tricky as your spells will get interupted ect so pulling 1 by 1 is a better way to do it ( casters are much easier cus of mana burn ) you wont be able to farm like a hunter so dont expect to.
Well im tired and i will edit if i tinhk off anything else ive used this spec for about 4 months now i love it asit lets me pvp/pve and i can still farm.
