This is news how? As the poster above me mentioned this was a problem all through Endwalker's life cycle.

If I recall the posts correctly, the first set of EXs we got were cleared with out healers, same as the savage raids

The next set of savage raids were also cleared without healers (or one), and so were the latest 4.

The only reason why healers are still "needed" in the game, is because FFXIV isn't like Elder Scrolls Online where you can use DF to trick a DPS into the healing role. You actually HAVE to have 1 of the 4 healers. If they ever changed DF to be like Variant Dungeons where you can queue as 1T/3Dps without being in a premade party the role will officially die. Cause its in the zombie stages as is.
