The problem is that it is extremely hard to balance tanks to feel tanky and satisfying to play while also making them dependant on healers because you require me to hurt in order to play your fantasy, but me hurting too often kills my fantasy.
I do not think this problem could be solved without heavily redesigning all tanks around defense and party protection (Perhaps more mechanics requiring tanks to do stuff like paladin wings instead of the current wack-a-dodge)

But i do not have faith on them doing any of this, so what i fear is for them to just nerf us to appease you somewhat, and neither of us truly getting what we want, which is more likely what is going to happen.
