The big one to note is that Diurnal Sect is a 10 percent healing buff instead of 15. So that changes a few things.
It also shows fey union cure potency as 480. for the fairy.
Benefic 440 vs Cure 1 450
Benefic 2 715 vs Cure 2 700
Helios 330 vs Medica 300
Aspected Helios 660 vs Medica 700
Aspected Benefic 1144 vs Regen 1050
Of course this doesn't solve the issue of how lilies and confession work for the whm but the diurnal sect healing buff is not as strong as we had thought at least according to the japanese tooltips.
