BWL/MC loot

Hello to evryone, since these bwl has opened i have farmed t2 tmog for warrior. And i cant get the shoulders i did farm today allday, looked up from wowhead what boss trop them but i still dint get it, it dropped evry other classes but dint trop warriors, i did get some warrior t2 items in mc what is strange, so i my question is are the loots broken and mixed between those two raids? or anybody got them by any sense somewhere else then it should?
