I have 3 level 50 retainers. Sometimes, all I get are crappy fish (no pun intended), coerul (sp?) meat, or some crap like that. But they have also brought back Blood Spattered Mark logs, Magicked Brooms, rare outdoor furnishings. indoor furnishings, and crafting/gathering materia. The item level 60+ doesn't really return anything better than the iLVL 50+,so I don't get too worried about that just yet. I think that's probably got to do with percentages. We all know how those work. Mining a node at 98% and get 1/2 miss/hit ratio. Worse yet, spend 300 gathering to increase HQ and still only get 1 of 4.
