We’ve corrected the following line to say the following. This was purely human error.
Combat and Subtlety have support for all weapon types, with Combat focusing on hard hitting direct damage and little bit of cleave damage with Blade Flurry, and Subtlety focusing on combat tricks and Bleeds.
We’ve also updated the note on Puncturing Wounds:
Puncturing Wounds: (Formerly Improved Backstab.) Now also increases Mutilate crit chance by a lesser percentage, and gives Backstab a chance to grant an additional Combo Point.
