RDM BiS?

[Lygas]

Oh then if that's the case with my BiS 1/2 hit is a DH which mean half of my hit are damage increased by 25%, det is kinda worthless there. With 1666.7 det that would make 10% damage increase but technically with 50% DH all my hit can be considered 12.5% damage increased.

Yeah, but wouldn't the 10% increased base damage still have a chance to dHit / crit / dCrit? I think it's less about stacking a stat at the expense of others and more about keeping stats relatively close together with a preferred stat that's above the rest.
