Bug Fixes

• Death Knight: Corpse Explosion: Fixed a bug where how much Runic Power the Death Knight had was affecting the damage done, and also increased the damage substantially.
• Druid: Savage Fury - Mangle (Bear) damage was being increased by a higher percentage than intended. This has been fixed, and in result Mangle (Bear) should see roughly a 16% damage reduction. Also fixed a bug with Savage Fury where the Rake bleed effect was not being increased.
• Fixed a bug with a Wild Mustard plant that was under the ground in Dalaran.
• Paladin: Repentance: Avenger’s Shield no longer breaks Repentance, but unfortunately, Seal of Vengeance and Corruption damage will break it again.  This will be corrected in a future patch.
• Paladin: Shield of Righteousness now properly shares a cooldown for both ranks.
• Priest: Mind Flay - Fixed a bug with targeting where you would not deal damage if not facing the target while channeling.
• Shaman: Elemental Shields was reducing flat physical damage, not a percentage. Now properly reduced by a percentage.

• Shaman: Fixed a bug where Thunderstorm (Elemental) was knocking back 15 yards, instead of 20. It should now roughly knockback the correct length of 20 yards.
• The Wintergrasp Aura should now properly update in all instances, transferring the buff when the zone control changes.
