Its april 2016 yet no healer stat weights???

[Granyala]

The stats in this game are incredibly simple, so i dont see how its poking in the dark with a stick.
Want more mana to do stuff>meld piety
Want to miss less when dps'ing>meld accuracy
Want to cast faster>meld spellspeed
Want more consistent higher heals>meld determination
Are you a SCH?>meld crit (also if you want significantly higher, less consistent heals).

You have no idea how we think do you?

Do I know how much benefit +x spell speed gives? No.
Do I know how much benefit +x determination gives? No.

So how am I assess what would be more useful to my character?
Right: I CAN'T. Because I do not have any data at all.

That's why I call it "poking in the dark with a stick".

Yes all stats are beneficial. However, I do not know how well a WHM scales with SS.
Maybe the scaling is crap. Maybe I'd get more effective heal power from det because it scales better.
That's where normalized stat weights come in.

Whether they display %ages or not is rather irrelevant unless you need to reach some form of haste plateau and after reaching that, divert subsequent materia slots to another, more useful stat. I don't think that there are such plateaus in this game that can be reached (stat customization is fairly limited), so it's rather irrelevant for us now.

Is this even close?

Hit the nail right on the head.
