Enhancement: Agility and Mastery, little bit of Haste - Because Agility gives me good attack power for my auto attacks however Mastery gives me good in magical effects.
Elemental: Mastery and glitchy-mitchy into Haste - Unexplainable.
Restoration Shaman: Crit and Spirit - Crit for mana return, Spirit for having something back when I can't crit.
Windwalker: Haste, till I hit 11 regeneration, then crit. Meanwhile getting good Agility - Haste for my energy regen, so I can use more heals and abilities, Crit to have higher heals and ability attacks. And Agility to top of Crit and dmg/heal increase overall.
