With my limited resources, I have used non-BiS (but closeish for non-crafted) gear to see if the stat weights are in the right ballpark. Spoiler: They ain't.

Link: more numbers version.

Less numbers version:
STR: 1.000
DET: 0.572
CRT: 0.210
WD: always use your best weapon lol
SS: 0.196

I used EMX's spreadsheet to calculate the potency of weaponskills and the effects of skill speed and crit. I did make some substantial changes: e.g. GL3 haste on auto-attacks is considered here, and the rotation is the current standard (ToD every 15 GCDs) instead of the one it was using (alternate Fracture and ToD every 10 GCDs). I feel like it may be overestimating the average rotation potency slightly.

This shouldn't change how to itemize properly, though.
