Affliction question:
I checked my character at AskmrRobot and it suggested that I geared for Haste and used Grim of Supremacy on single target fights....
All guides I've read say Mastery is the go-to stat and Grim of Service should be used on single target fights.
Are they just wrong at askmrrobot or do any of you fellow affliction locks have any good experiences with haste stacking and grim of Supremacy?
