Love how you can talent it if you want without talenting soothing mist which is required for it to work like 10/10 game design Bliz congrats very new player friendly 
Like should either make Soothing Mist base line, change its activation method with a seperate spell that marks a target for it or add somewhere in big bold red letters that it requires the Soothing Mist talent.
to be fair, the description does say ‘When you channel soothing mist…’
but it is a pretty weird location for it granted.
I wish it would follow the last person you cast RenMist or Vivify/Env on.
Tbh that was my first thought but don’t think they’d want to make it that easy on BM and WW cause they hate non Healers healing.
RenMist is only in the MW Tree. So having JSS heal the last person who was RenMist-ed wouldn’t impact the other specs and would be an easy way for them to make JSS useful to anyone not running a pure soo mist build.
With the 2-3 RenMist charges we would have a degree over how/when we can move it around too, and it would be smoother in general to keep JSS doing it’s thing. It feels really bad to stop doing what you are doing just to get JSS going.
