Have enough pinks been collected in the Nightmare Map to verify that certain bosses don't drop specific items? From the recent patch it seems that it is in line with all the other maps as far as any pink can drop from any Boss/Mini Boss. On a side note good luck with the group of lv 30s in Nightmare I tried with my lv 30 bear and they hit extremely hard. I have the best gear I can for that level(non Nightmare items) and died constantly. I admit that playing a Bear Tank is not my strong suit I play my mage the best(always preferred healers).I would definitely recommend at least 2 mages that know how to play and stagger the heals for a successful run at lv 30.
