1. Is still a thing because it doesn't matter if I use a GCD or an oGCD. Damage is still infrequent. For damage to be more frequent, fights would have to change. Healing with Benefic 2 over Essential Dignity or A. Helios over my 4 oGCDs is just as engaging. So yes, fights would need to be rebalanced still if you want healing to be more fun, and that's not even including how our healing kit also would likely need to change.
2. Is on SE's dumb part. And I'm not waiting for them to reintroduce support tools OTHER than mitigation, which was my point. Addle, Feint? I don't care if we have those. They're a press of the button and done really and nothing truly interesting to deal with. We have our own versions of mitigation. I want some support OTHER that mitigation. Where is MP restore? Gone because we have 0 mana costs (another thing that makes healing boring btw). Why DON'T we have an AOE esuna and fights designed around using it? Why again CAN'T we use Repose/Sleep on a boss as a way to Interject? THOSE are the support tools I am asking for and SE stubbornly refuses to give. So again - damage.
3. There is 0 reason why all healers cannot have a Phlegma and another DoT to make solo content less tedious. That isn't a damage rotation like a dps. Do all healers need SCH's dps kit in SB? No. But does it need to stay 1 DoT and 1 nuke? Also no. AST or any other healer can have a small dps kit if there is to be more of a focus on something else or for it be easier, but there is 0 reason for one to stay as it is right now.
I agree with you, however that not all the healers should be brought to SCH's SB level, but ALL of them do need to be changed.
