PRIMEVAL FEAST

 * The Sacrifice debuff itself no longer kills its target.
 * The Sacrificed targets can still be killed by mobs if the mobs are not tanked.

INFERNAL DAWN

 * Increased time between minion spawns in the first phase of the Laethys encounter.
 * Increased casting time of Annihilating Flare.
 * Decreased damage done by Golden Cleave.
 * Molten Gold will no longer be cast immediately after Metallic Orb.
 * Increased duration of Stoneseer's Wisdom.
