This tier has been a nice step forward in opinion. It doesn't address the post-prog healing gameplay because we still reach a point where we simply outgear P5-7 enough to entirely oGCD them. Purgation is probably the only mechanic in those three fights that may still need a GCD shield but progress is progress. P8S is the first Savage fight in six years we literally can't oGCD heal. I want to see more of this because it's actually making us utilize our full kit regardless if it's a safety clear or a log run.
Of course, this does nothing to address the content below Savage. Which remains a snore. I like the concept of Variant Dungeons but it really highlights how poorly thought out the Healer role is. With a four person comp, healers are entirely irrelevant. That should never be the case, regardless of the content's intended difficulty. So the dev team still has a ways to go in making the healing role interesting again.
It isn't fact though.
White Mage was the only healer essentially punished for utilizing their own job gauge. Someone wanting their job to be at a competitive level to its respective counterparts doesn't necessarily make them a "green DPS". At least not in the context you're using that term. Furthermore, it wasn't a minimal DPS. In fact, let's review! Grabbing a random top ranked White Mage from P6S. They used Rapture 21 times. At 310 potency from Glare III, this would equate to a 2,170 potency loss throughout the fight. A rough estimation puts that well over 500 rDPS just... thrown away for no tangible benefit. What does White Mage offer the other healers cannot do better without suffering a massive damage loss? Absolutely nothing. Those big "burst heals" aren't relevant. Not only is shield healing and mitigation objectively better than regeneration, Astro can easily handle the load just fine.
In other words, there is no reason to bring a healer whose main gimmick is "healing" at a loss. This isn't a "self-created" problem but a poor balancing one.
The irony here is you bring up FFlogs, which yes, have influenced the community on the whole. It's also the only reason Savage retains any relevancy outside of Ultimate gearing. Without that website, Savage would be entirely dead content within 2-3 months. If not sooner.
