I hate that this thread exists because it absolutely NEEDS to. Thank you OP for spending your time summarising all the wrongs with healing. I couldn't agree more with all of it.
Since ARR I have played healing roles in savage tiers. When I went DPS in savage, the only thing I wanted to do was go back to healer. I love healing but with each passing LL in which we go ignored, my disdain for this entire situation really just beats out my love. At least acknowledge it. At least tell us you're aware. Just a few words to ease our minds.
