(also check the thread I've started for this:
Scaling Coefficients)
*These are the results from using the latest trunk build of SimCraft (build 1960) which is updated for PTR build 9733 of 3.1.0.
Do not use for earlier versions.*These tests were run with profiles manually increasing or decreasing stats compared to the baseline rather than using calculate_scale_factors until a possible bug is resolved with that.
The tests were run with 30000 iterations.
There were 3 "sets" tested.
The sets were:
==========
1) BiS T8 gear set and increasing stat values in turn (except for +hit rating).
2) BiS T8 gear set and decreasing stat values in turn (incl. +hit rating).
3) BiS T7 gear set and increasing stat values in turn (except for hit rating).
There were of course baseline BiS T8 and BiS T7 profiles executed.
The results:
========
For set 1 (BiS T8 increasing stat values):
sp: 1.498
crit: 1.0696
haste: 0.9672
spi: 0.3412
int: 0.3336
hit: 2.019
For set 2 (BiS T8 decreasing stat values):
sp: 1.5128
crit: 1.0796
haste: 0.9788
spi: 0.2964
int: 0.2968
hit: 2.019
For set 3 (BiS T7 increasing stat values):
sp: 1.4112
crit: 0.9768
haste: 0.9292
spi: 0.2888
int: 0.2848
hit: 1.745
Averaging out Sets 1 and 2 gives an idea of the scaling factors at the T8 BiS level:
sp: 1.5054
crit: 1.0746
haste: 0.973
spi: 0.3188
int: 0.3152
hit: 2.019
Averaging Sets 1, 2 and 3 gives an idea of scaling factors across the expected gear range etc:
sp: 1.474
crit: 1.042
haste: 0.9584
spi: 0.3088
int: 0.30587
hit: 1.92767
The PP values for the Average of Sets 1 and 2:
sp: 1 PP
crit: 0.71383 PP
haste: 0.64634 PP
spi: 0.21177 PP
int: 0.20938 PP
hit: 1.34117 PP
The PP values for the Average of all 3 Sets:
sp: 1 PP
crit: 0.70692 PP
haste: 0.65020 PP
spi: 0.20950 PP
int: 0.20751 PP
hit: 1.30778 PP
For the purposes of gearing up towards the BiS T8 set from a BiS T7 baseline, we're probably better off using the Average of all 3 Sets PP results.
So, I'd propose using:
sp: 1 PP
crit: 0.70692 PP
haste: 0.65020 PP
spi: 0.20950 PP
int: 0.20751 PP
hit: 1.30778 PP(numbers subject to change if there are any upcoming Priest changes on PTR).
The resulsts are to 5 decimal places because we tend to multiply our coefficients with stats that are 3 to 4 digits big and we give results to 2 decimal places.
However if you want simpler 2 decimal place values for easier number crunching:
spellpower: 1 PP
crit rating: 0.71 PP
haste rating: 0.65 PP
spirit: 0.21 PP
intellect: 0.21 PP
hit: 1.31 PP
