Atma Fate System Broken

[Felis]

I'm almost on week 4 and 0/12 still. I feel your pain this system sucks.

If it wasn't FATEs it wouldn't be so bad :/

Yes
It should be with something like this:

And the greater the points, the better the droprate. And each run drop only 1 atma at max for the whole party (8*12 runs minimum to give everyone in the party all atmas), but once you have the 12 you don't need to do it again for the other weapons.
