Mastery >= Haste > Intellect > Crit > Versatility
Stat Outline
Intellect: Raw damage increase on everything.
Haste: Makes your cast time and Immolate ticks faster and shortens your cooldown on Conflagrate.
Mastery (Mastery: Chaotic Energies): Passively increases your damage and reduces your damage taken, in addition to a random component/amount of both.
Versatility: A weak damage multiplier and damage reduction.
The best way to calculate stat priorities for your character is to "sim" your character
