I am thinking about a 12mnk/6rgr/2ftr or rog... But now I can't remember exactly what was changed about TWF after update 5. As of the last official word I could find (quoted below), a 12mnk/6rgr with windstance3 and tempest1 should be getting 107.5% main hand, and 90% off-hand proc.
But I remember reading that tempest1 +10% was removed, or didn't work with handwraps... Does anyone know for sure?
