In the future will the loot from Nightmare Mode operations be of higher quality than that of Hard Mode operations? I recently downed SOA 16 NM and all of the mainhand tokens were for columi items. Loot from that tier drops from HM FP's and 8 man normal mode operations. Is it this way because there was not enough time to itemize nightmare mode before launch or is this the way all future operations will be? Also, what is the airspeed velocity of an unladen swallow?
