As a rdm who has not done dynamis in a long while I was in Tomodachi a well known HNM LS on bahumut we did many many dyanmis's and we always had the worst af drop rates. I NEVER once saw one piece of RDM af drop hence I own none.
Two members of tomo have recieved rdm drops the weekend I had my wisdom ntetth out I wasnt on LMAO. But honsetly we on more then one ocation had NO drops for an entire dynamis clear boss kill and all. Least in glacier and only thf drops in xcarbard. We always had at least 1 thf and eventually two thfs with af th+1 and one with an thf knife. I think to this day becasue in my real life I have bad luck it was me LOL. 75 capped about 40 merits no af2 or crimison partrs excepot hands. GAVI
