Kind of appears you're either lucky or favored. Others have not been so lucky, at least in my guild. I'm not going for the Calender and I've 3 and have 14 fragments. I've gotten 2 from daily quest twice, the rest of the days only 1 fragment. The extra were from picking the key more than once. I'd seen lots of keys, just didn't go for them. Others wanting them seem to be lucky to even find one to go after. This aspect of the game is luck unless of course one can actually be favored. So of course, feedback is pretty much based on if you're going for the calendar, whether or not you are lucky. It's the gambling aspect of the game that those of us who play only because its also a strategy game, dislike, or actually hate.
