WARFRONT ACCOLADES

DUNGEONS AND RAIDS

• Many dungeon terrain shortcuts have been fixed. Please bug report any that are still an issue!

SOULS

• Recasting buffs like Rogue poisons will now replace the existing buff rather than a random one.
• Dominator: Fixed an issue where Charged Shield [Rank 5] and Mass Charged Shield [Rank 4] would double-proc when triggered.
• Marksman: Vampiric Munitions: Fixed a bug where the healing siphon caused the Marksman to break stealth when the debuffed target was healed.
• Nightblade: Fell Blades: Fixed a bug where the healing siphon caused the Nightblade to break stealth when the debuffed target was healed.
• Pyromancer: Burning Bonds: Fixed an issue with the Unbreakable Bonds ability where Burning Bonds would only root a PvP target for 4 seconds instead of 8, even if the target was not under the effect of diminishing returns.

CLIENT

• Client optimizations!
• The game now tries to work around a bug in AMD Llano CPUs (AMD models A4-3XXX, A6-3XXX and A8-3XXX) that was causing frequent crashes. If you use one of these processors you should notice improved client stability.
