Tank healing is to high

So we're at the point where hardcore content is what the entire game is balanced around? We're really gonna do what WoW did which is the main reason that game's dying?

Always has been. If you balance jobs around the easiest content in the game they won't be able to handle the harder content. WoW is dying for many reasons, but none of those reasons are classes being balanced according to the demands of Mythic raids. If anything WoW struggles with the opposite, making sure classes are balanced well enough to be able to use them in such difficult content.
