• During Phase 2 of the Lady Vashj encounter in Serpentshrine Cavern, there was a significant chance that a Coilfang Strider could spawn at a particular point that would cause the creature to evade. The Strider evading would then reset the entire encounter prematurely. We've made a modification to the spawn point that should prevent this behavior.
• During Phase 2 of the Al'ar encounter in Tempest Keep, Al'ar occasionally charges at a random player. The damage dealt by the Charge was severe enough to immediately kill a lightly armored target even if the player was at full health. We've reduced the damage done by this Charge ability.
