Well I do have the Halfus Shoulders I thought it was only better to go with the Halfus Shoulders and 4pc if you had access to Herioc gear, is that not the case? As my guild has decided to not bother with Herioc's I figured that the 5% extra damage on CS from the pvp gloves would better. I also remember that Mastery and Crit go in tandem as any criticals attacks would increase the Mastery portion of your damage.
