I agree that latest changes to Elemental and to some extent Enhancement are controversial and that is why I created feedback and suggestions threads on PTR for them to point old and new issues and offer solutions. Here is the link to Elemental Shaman post (and it contains links to other Shaman specs posts if you are a non-Elemental main) - 11.0.5 Elemental Shaman Feedback And Suggestions
If you have additional suggestions - you can post them in comments in according specialization thread. Let’s hope that since Shaman rework is still in progress (and it likely would continue since for example there are currently no fleshed out lava and lightning builds like stated in design goals for Elemental) Blizzard would read this feedback and take it into account.
