That's disappointing to read because it's what I feared. I know it was the same effect at the start of ShB and was hoping this time they've resolved an issue with gear disparity. I'll still see for myself and when I get there and find it's as you say, then my biggest bit of feedback for healers this expansion will be to solve the iLevel disparity. They refuse to do the easy solution the healer forums have been pushing for in the entirety of Shadowbringers and YoshiP has stated as such, but this would at least fit their vision more.
The biggest issue for healing I feel is that:
The jobs are designed best to be more healing focused and less DPS focused.
The content is more DPS focused and less healing focused.
So naturally these two principles don't work together and end in monotony. And they won't adjust the job to better manage the DPS focus, so the content ought shift its focus. And seemingly it does until people are geared.
