It's a change to Improved Water Shield as shown below, which are more updates not shown above:

[quote='Blue
Restoration

Healing Way doesn't stack up to 3 times anymore and now increases the effect of subsequent Healing Wave spells on the target by 18%. (Up from 6%)
Improved Water Shield has been changed to - You have a 33/66/100% chance to instantly consume a Water Shield Orb when you gain a critical effect from your Healing Wave or Riptide spells, and a 19.8/39.6/60% chance when you gain a critical effect from your Lesser Healing Wave spell.

Glyph

Glyph of Windfury Weapon - Increases the chance per swing for Windfury Weapon to trigger by 5%. (Old - The attack power bonus on the additional attacks granted by Windfury Weapon is increased by 40%.)
Glyph of Fire Nova Totem - Reduces the cooldown of your Fire Nova Totem by 3 seconds. (Old - Increases the radius of Fire Nova Totem's effect by 2 yards.)
Glyph of Fire Elemental Totem - Reduces the cooldown of your Fire Elemental Totem by 10 min. (Up from 4 minutes)
Glyph of Astral Recall - Cooldown of your Astral Recall spell reduced by 7.5 min. (Up from 2.5 min)
Glyph of Renewed Life - Your Reincarnation spell no longer requires a reagent. (Old - All stats increased by 5% for 1 min when you Reincarnate.)
Apparantly people were spamming LHW which had the same crit but shorter cast as HW which made IWS more efficient so they reduced the proc for LHW.
