I’m hoping there will be a mass thread on this. Two things I noticed:
5.6% Mana, 40 yd range, 2.5 sec cast
Heals the friendly target for a moderate amount, then jumps to heal the most injured nearby party or raid members. Healing is reduced by 30% after each jump. Heals 4 total targets.
CH back to smart healing the most injured ally
When you cast Chain Heal or Riptide, you gain the Tidal Waves effect, which reduces the cast time of your next Healing Wave by 40% or increases the critical effect chance of your next Healing Surge by 40%. Stacks up to 2 times.
This tells me that casting CH or RT gives 1 stack to TW, and you can store up to 2
