I don't want to be the person to parade around false hope. It's been years of healer feedback not being received and midcore-hardcore healers being forced to conform to the gentle healing style enforced on the entirety of the role in subtle ways during Stormblood and then in full force during Shadowbringers to now. All many of us have wanted is to move toward a role that can be both forgiving to casual players and beginners while offering midcore-hardcore healers more to work with in all forms of content, not just Ultimate.
Having said that, we have finally started getting our concerns actually acknowledged in the last several live letters both leading up to Endwalker and now. Yes, they're effectively dodging the substance of the issues we're bringing up and casually "resolving" them with "go play ultimate," but the fact that we're being heard at all is a big change of pace as healer discussion basically didn't exist in Stormblood and most of Shadowbringers. I will not say that they will listen to us eventually, or that we will eventually get what we want the way that we want it. What I will say, though, is that we're being heard. Maybe we're not being listened to, but we are being heard.
So don't stop asking the same questions until they're acknowledged properly. We cannot know how much of a difference that can make, if any, but if people continue bringing up the same thing, it means their solutions are failing, and there is pressure to address that. Is that enough pressure to matter? Perhaps not, but it's better than no chance at all. So be a broken record. Be annoying. Continue to repeat the same thing over and over, but remember to still be respectful and polite. Even if you don't think your respect is earned, it's much easier to ignore people being hostile than it is to ignore people being patient and respectful.
And if you want to try and do something about it now, your best bet is to go on a healing hiatus and play DPS. I'm not telling you that you have to do this, nor are you wrong if you continue playing healer, just reminding everyone that it's an option. If the healing population were to drop, it's harder to ignore that.
