Yoshi-P: "If you want more engaging content, go play Ultimate"

[SieyaM]

While it certainly wouldn’t revolutionise anything we have to acknowledge there is must be a reason why healing is so singularly unpopular in this game, I don’t think attempting changes to try to figure out why is necessarily a bad thing

Because there is nothing particularly engaging about it, you spend most of your time DPSing with the singular spell you have for it without ever really working towards something. DPS and even tanks I believe have some kind of burst phase that you are using your rotation to build towards, even if it's all on a 2 minute timer now. As a healer you have none of this, just DPS spam while using your oGCD kit to heal whatever there is.
