I beleive the pre-DR raitng conversion factor is 0.94 rating per point strength
I did a brief search but I'll admit I didn't but any huge effort into it. Wondering if anyone could tell me the current lvl 90 str -> parry conversion before DR and such for a warrior. Without buffs or with buffs doesn't matter but would need to know which it was.
0.9304 to be somewhat exact (885/951.158596 is the exact ratio)
