Fractured front troggs nerfed?

i used to love this spot for potion of treasure finding. the troggs spawn in groups of 5-10 and are tanked by NPCs. since prepatch, they drop almost no gold and literally nothing else. no tiny treasure chests, no cloth, no boes, not even grey items. i distinctly remember farming in deepholm during original mop to sell embersilk bags. so what happened???
