Blizzard has posted updates to the Patch 12.1.5 Patch Notes, which includes a buff to Subtlety Rogue!

Official Patch 12.1.5 Notes

CLASSES

ROGUE

Subtlety
All ability damage increased by 14%.

​ Developers’ notes: We’re increasing Subtlety’s ability damage to compensate for the changes to Subtlety’s Shadow damage modifiers and any occurrences where those modifiers were previously applying their effects more than once.

DELVES

Increased recipe drop rates in delve.

HOUSING

Reduced the cost of all crafted decor from pre-Midnight professions.
