Its april 2016 yet no healer stat weights???

I can't speak for every other MMO, but in this one secondary stats are not a straight line (except DET more or less).

Adding your 800th Spell Speed gives you about 15% more of a proportional increase than you got from adding the 1st one in terms of casts, but has a proportional decrease in DoT/HoT ticks. Crit hit rate has an even sharper proportional increase than SS. DET is a fairly straight line on damage increase, which means a proportional decrease.

Yes stats scale exponentially.
Which is why simulations and all subsequent calculations are done for specific gear points.
Basic math. It is called "Linearisation".

Obviously stat weights are only valid for your character if you are near the point where they have been derived.
And yes again: every Everquest clone MMO works that way.

The very first response made perfect sense, though. There's no real purpose to have healer specified statweights.

I never disputed that.
Still many answers were quite rude.

This is precisely how FFXIV is designed. No one takes damage and then all of a sudden everyone takes 10k. That crit Medica means you cast it once instead of twice.

No matter how you slice it: crit WILL generate unintended overheal.
Also the crit might not happen when you need it and might happen when you don't need it.

Though this has been a religious debate amongst healers in various MMOs for as long as I can remember. Some like it, some don't, ultimately both setups get the job done.
It's ultimately up to personal prefs.
