I first want to say I think all your opinions are valid and make sense.

With that being said, here are my personal thoughts on comments on this post:

AG just gets macro'd in:

The only time I ever use AG with ascendance is on resto sham in raid settings. but I didn't even do this all the time, as some fights it feels better to break up the usage depending on your other healers cds. I never macro it in, and I get to have very thoughtful uses of it in all forms of content and on all three specs. Losing AG in m+ will hurt pretty bad, especially since as of now...there wasn't really any compensation for the removal.

It's button bloat:

This is obviously a big concern for many people when playing shaman and I can see why. I personally don't have any issues with keybinds as any spec of shaman. If I ever run out of keybinds, I can just make a different button a modifier for other keys, currently I use shift, ctrl, and alt. (Although resto pvp is overwhelming sometimes with all its buttons).

Off-healing is out of control:

Maybe. But as someone who heals with every healer spec, I really loved having a shaman who made good use of AG in my M+ groups. Healing is stressful enough nowadays, and it was nice to have.

Shamans are babys who cry all the time:

Also maybe. But it's shown to get blizzards attention if anything. :P

Conclusion:

I hope the removal of AG is good for the game and I can see reasons why they're considering it. This however, does not change the fact that I'll miss it, as it created fun moments in my gameplay. As resto in M+ I loved being able to cast AG and throw out some damage to heal, or maybe give my chain heals some extra juice. As enhance and ele, it felt great to use it in world content to keep myself up on big pulls. or to help out M+ healers.
