At this point, I don't see healing ever being really "fixed". Things are the way they are and that's the way they are going to be. I have given up hoping to see things change and I do not believe we will really ever see healing getting fixed. All of the new games I have seen have roles that are mostly DPS with some nice heal gimmick.

Though... I wouldn't be surprised if FFXIV converted healers into utility DPS and made healing potions a thing again. A DPS with a healer utility would pop a 2 or 3 min CD heal on the group and back to DPS. Otherwise, your on your own if you get hurt, use your pots and stack VIT.
