Its april 2016 yet no healer stat weights???

[Yhisa]

And if the det values are true then i got to adjust my gear all over again as going by this thread det is bad

Which then leads to spell speed and crit being stacked..... But what i never understood is if spell speed was bad.. Why did black mages stacked it always? And this is in 2.0 and 3.0 (they only had leylines in 3.0)

And they had firestarter and thundercloud procs... But yet still stack speed

WD: 3.0
MND: 1.0
CRIT 0.25
SpS: 0.30
DET: 0.08

Looks good.
Yes we did calc with 100 SpS, which is why I said that it is worth more than crit. With the usual cave eat that it's value drops to pretty much the HoT bonus only the moment you stop casting every GCD.

DET is to be avoided like the plague then it seems.

Timings on Enochial & Astral/Umbral my dear. The more haste you have the more lenient they get due to shorter casts and the less likely you'll lose Enochian at the last millisecond of the cast.

Crit/speed
Vs
Det/ speed
Vs
Crit/det

If DET is this useless as the numbers suggest, there is no point in testing this.
Excluding det you have 2 choices:

Either go for accuracy if you are a raid healer and your raid relies on your DPS.
Or go for Crit/SS.

If you heal with HoTs, you should probably favor SS (can HoTs/DoTs even crit?), if you operate with shields, you should definitely favor crit.

Piety is an option if you truly have mana problems, but I doubt that a WHM should be used as "primary off DPS" due to shitty mana management. No clue whether AST has mana problems when DPSing a lot.
