Discipline Priest leveling guide
Discipline is the Priest who hardly ever takes damage. Power Word: Shield absorbs the first hits of every fight, 
Borrowed Time then speeds up your next spell, and 
Penance hits an enemy three times or heals you in a pinch. Leveling is slower than Shadow, but you stay ready to heal a dungeon group at any moment.
Strengths and weaknesses
- Power Word: Shield with
Reflective Shield and 
Divine Aegis makes you very hard to kill. - Penance,
Holy Fire and 
Smite deal decent holy damage. - You can heal any dungeon along the way without changing talents.
- Slower kills than Shadow, and groups of enemies take a lot of mana.
