Priest Leveling Spec - The Best Talent Spec For Leveling a Priest Fast

Each Priest Leveling Spec has its advantages andImproved Spirit Tap 2/2
disadvantages. Most of the people say that theImproved Shadow Word: Pain 2/2
Shadow Spec is the way to go, due to its highShadow Focus 3/3
damage output. But it is not exactly true. The shadowImproved Psychic Scream 2/2
build becomes very powerful only at level 50. So theImproved Mind Blast 2/5
fastest Priest Leveling Spec is in my experience: fromMind Flay 1/1
10-49 as Holy, from 50-80 as Shadow.Shadow Reach 2/2
What talents to choose for Priest leveling spec? In myShadow Weaving 3/3
experience the best spec looks like this:Silence 1/1
Levels 10-49 (7/27/3)Vampiric Embrace 1/1

Healing Focus 2/2How to get the most out of this Priest leveling spec?
Improved Renew 3/3My recommended spell rotation:
Holy Specialization 5/5From 10-49 as Holy Spec it would look like this:
Divine Fury 5/5Smite > Mind Blast > Shadow Word: Pain >
Desperate Prayer 1/1Power Word: Shield > Devouring Plague
Holy Reach 2/2Then form 50 to 80 as Shadow the spell rotation is:
Searing Light 2/2Power Word: Shield > Vampiric Touch > Mind
Spiritual Guidance 5/5Blast > Vampiric Embrace > Shadow Word: Pain
Surge of Light 2/2> Devouring Plague > Mind Flay
At Level 50 re-spec to ShadowTo conclude my thoughts, if you want the fastest
Shadow Talent DistributionPriest leveling spec then first level as Holy, then at level
Spirit Tap 3/350 re-spec to Shadow build.
