I like them. Some of them, like efrils and phitzell amulets are really usefull for lower levels. But they are achieveble one in a life time. Why not make some of the rewards achievable every month or so? I don't think 5 phitzell amulets or one flying dust each month would break the game. This way we can have more things to do other than picking resources. And have some other opportunities to progress.
