Venomous Set stats bug or intentional?

[Ravager]

I noticed the mage and war versions have 52 primary stat, 19 other stat.
The rogue version has 52 dex, 32 str for amulet and 52 dex, 28 str for ring.

13 stat difference on amulet and 9 stat difference on ring. Is that intentional? Otherwise, please add to the 2nd stat of the item.
