Yes the extremely bad luck experience really dispressing some players.
I think if there is a cap for atma, for example max one per day, and the quota can be carried would be less painful for those having bad luck.
Moreover, max receving one book per week also good.
If it is a long term quest, the design should not let players able to complete in a few days.
As everyone know, complete it asap = easier. For example the FATE to unlock CT, without the nerf late comers really hard to clear the FATE to unlock it.
