I know you said to put this in bug reports, but I guess it's more of a suggestion? Anyways, I've killed almost 15 Griffeys (5 of which were on x2 drops) and 5 Manons, and have yet to obtain a single Mastery Book. I know it's possible that I'm just getting really unlucky, but I feel like it'd be good to increase the drop rate on mastery books from theses bosses just a little bit, because as of now it seems like I'm going to be spending a LOT of time in Leafre.
There is a 'suggestion' type you can choose when bug reporting. If you can re-post there would be great.
