I just read through the latest changes going into effect for the next update and unfortunately, Rogue didn't make the cut.
Details about her bug can be found here:

Basically, she is correctly reducing the duration of some debuffs but not others. Incinerate, armor break, shock, and others still stay on Rogue for the full duration despite her natural abilities.
The bug was acknowledged last Summer and a fix was almost rolled out, but it was called back at the last minute.
Is anyone looking at Rogue?
