• CH better and requireing less mp5 stacking for AOE fights. yes plx
  • Edit: Also CH decreases by 40% each jump instead of 50%
  • CH will jump 10 yards instead of 8
• Something about Healing Way....well...it can't get much worse. Nobody takes it.
• Nature's Swiftness on a 2 min CD. Sure why not?
• New Totem interface and the ability to drop all 4 totems at once with potentially different configurations. Yes. Plx.

None of this helps much w/ pvp (well except for maybe totem stomping and NS somewhat) but IR happy.

 PTR Patch Notes 6/18/09

Shaman

• A customizable totem bar will now be available for shaman allowing the storing of 4 different totems. These totems can be placed on the ground at once in one global cooldown for the combined mana cost of all 4 totems.
• All Shocks now have a default range of 25 yards, up from 20 yards.
• Base health increased by approximately 7% to correct for shamans having lower health than other classes.
• Chain Heal: Jump distance increased to 10 yards. In addition, the amount of healing now decreases by 40% as it jumps to each new target, instead of 50%.
• Ghost Wolf: Can now be learned at level 16. While in this form, snaring effects may not bring the shaman below base normal run speed.
• Talents
  • Enhancement
    • Shamanistic Rage: Cooldown is now 1 minute, down from 2 minutes. Successful melee attacks now have a chance to generate mana equal to 15% of the shaman's attack power, down from 30%.
  • Restoration
    • Ancestral Healing: The buff from this ability now reduces the physical damage taken by the target by 3/7/10% instead of increasing the target's armor.
    • Cure Poison and Cure Disease: Combined into a single spell, Cure Toxins.
    • Earth Shield: Dispel effects will now remove charges of Earth Shield rather than the entire aura.
    • Healing Way: Redesigned. Rather than providing a chance of increasing Healing Wave spells on a friendly target, this talent now innately increases the effectiveness of the shaman's Healing Wave by 8/16/25%.
    • Mana Tide Totem: Totem health now equal to 10% of the shaman's health.
    • Nature's Guardian: Redesigned. Now has a fixed 100% proc rate, has a 30 second internal cooldown, and increases the shaman's maximum health by 3/6/9/12/15% for 10 seconds.
    • Nature's Swiftness: Cooldown is now 2 minutes, down from 3 minutes.
    • Tidal Waves: No longer reduces the cast time of Lesser Healing Wave by 30%. It instead now provides +25% critical strike chance to Lesser Healing Wave, along with the previous 30% cast time benefit to Healing Wave.
    • Improved Water Shield: This talent now has a 10/20/30% chance to be triggered by Chain Heal, and the charges of Water Shield are no longer consumed by this talent.
