Reforging allows you to modify the secondary stats on your gear. Use this guide to determine the best strategy for reforging your stats so that you can optimize the performance of your Restoration Druid.
Intellect > Spirit > Haste (Breakpoint) > Mastery > Crit
1. Optimize Spirit
On any gear without Spirit, reforge the weakest stat (see stat priority) into Spirit. Do this until you have enough Spirit to provide you with just enough Mana to survive the typical PvP encounter.
2. Optimize Secondary Stats
On any items without Haste or Mastery, reforge the weakest stat (see priority) into Haste until you reach a Haste breakpoint (3043 or 3028 rating). After that, reforge for Mastery or Crit as available.
