And all the weapons do is swap your stats around, so if you think you are hitting the dummy for more or less with either weapon (if you reforged right you should have similar secondary stats), that just means you're doing your gemming, enchanting, or something wrong.
Currently a 14/14 Holy Paladin and 10/14 Discipline Priest in Siege of Orgrimmar
Formerly voidspark - 8/8 Demonology Warlock and Restoration Druid in Dragon Soul
