Classes - General

• Several persistent ground effects now display different visuals for hostile and friendly players. The following spells have the same visual effects for friendly players, but new alternate visuals for hostile players: Ring of Frost, Consecration, Desecration, Wild Mushroom, Flare, Ice Trap, Power Word: Barrier, Smoke Bomb, and Hand of Gul'dan. As a general rule, the alternate effects have a red tint or hue indicating they are created by an enemy player.

Druids

• Efflorescence has been redesigned. It creates a healing zone at the feet of a Swiftmend target, but this healing zone now restores health equal to 4/8/12% of the amount healed by Swiftmend to the three most injured targets within 8 yards, every 1 second for 7 seconds. This periodic effect now also benefits from spell haste, but the individual ticks cannot be critical effects. In addition, Living Seed is no longer a prerequisite talent for Efflorescence.

Mages

• Improved Arcane Explosion now also reduces the mana cost of Arcane Explosion by 25/50%.
• Ice Barrier base damage value has been increased by approximately 120%. In addition, the benefit from spell power has been increased by approximately 8%.
• Glyph of Frost Armor (new glyph): Frost Armor also causes the mage to regenerate 2% of maximum mana ever 5 seconds.

Warriors

• Colossus Smash now ignores 50% of a hostile player's armor (PvP), but continues to ignore 100% of a non-player character's armor (PvE).
