Al though the rework is appreciated it still doesn’t feel like it does the job imo. So here’s my suggestion to give the mistweaver a bit more oomf:
Replace Invigorating Mists (the renewing mists cleave heal) with Tears of Morning, so that talent does the (incresed0 cleave healing for both vivify and enveloping mists.
Add the renewing mists spreading component to Dancing Mists though, so giving renewing mists a 10% chance to spread each tick and another everytime you cast Vivify or Enveloping mists on it.
Finally add a new last tier option to replace the Tear of Morning, which does the following: Whenever you cast vivify enemies within 5 yards range take X % of damage of the healing as damage over 3 seconds (similar to the Thorghast ability) and whenever you channel Soothing Mists you get a charge of something which increases the damage done and reduces the casting time of Crackling Jade lightning.
The reasoning is to give fistweavers more AoE footground and ranged mistweavers more damage potential.
