It's actually no different than when we jumped from Heavensward to Stormsblood, now that I've hit 80 and done some preliminary testing.
~~Data points here~~
Methodology
Get ten Cure I data points and get that average in each expansion content that would be deemed "low tier" and "high tier" using min ilvl sync. It's a small sample but large enough to get a reasonably accurate average.Be sure to remove Echo in applicant content such as 8-man Savage raids.
- The Soul of the Creator (Savage) [high tier Heavensward] which has a min ilvl of 255 resulted in a value of 5,786.5 per Cure
- Ala Mhigo [low tier Stormsblood] which has a min ilvl of 280 resulted in a value of 6,302.9 per Cure
- The jump from high end Heavensward to low end Stormsblood was a jump of 8.92%
- Alphascape V4.0 (Savage) [high tier Stormsblood] which has a min ilvl of 380 resulted in a value of 12,381.6 per Cure
- Currently, I just hit 80, got my AF gear [low tier Shadowbringer] and I have an ilvl of 418. My cures resulted in a value of 13,445.0 per Cure
- The jump from high end of Stormsblood to immediate low end Shadowbringer was a jump of 9.47%
So, we did indeed get a minor increase in our healing potential in a similar vein that we jumped from the previous expansion. I also put a few more differences on my chart just for my own analysis and thoughts later, but it's there for people to see.
With the above notes, it seems the power curve is as intended.
This is also my point - let's not just work with "feels" and posters should be presenting any test data - let's be scientific and factual about our analysis so we can be unbiased with how healing has changed.
