The thing with that is that they've effectively softened everything up to a point that it's actually tanks that are obsolete, because a DPS or a Healer can easily survive a "tankbuster" in generally anything below Extreme Trials. And as they made tanks obsolete, they also gave WAR and PLD more than enough tools to actually function as healers.
But as tanks can heal themselves, and everything hits for barely anything... Healers have more downtime, which inherently isn't a bad thing but they just absolutely refuse to give Healers anything to do with said downtime. All we get is spamming 1. Occasionally pressing 2 to reapply a DoT.
