I used the good old snippet tool to create a custom talent tree for Enhancement shaman for Shadowlands. I used the abilities we had in the past or stole from elemental and created nothing new. I actually thought most of the changes I made can make a big change, especially in survivability. Also, Fire Elemental would be baseline and brought back to Enhance. I hope the link works. I wish I could put an image or link in a post on the wow forums.
