From latest PTR build:
  • Shaman
    • Earth Shock: Redesigned. This spell no longer interrupts spell casting, but rather reduces melee attack speed by 10% for 8 seconds (exclusive with similar effects such as Thunder Clap).
    • Wind Shock: Has been renamed Wind Shear and no longer shares a cooldown with Flame, Frost or Earth Shock.
    • Maelstrom Weapon: Now also has a chance to reduce the cast time of Hex.

spiffy!
