I don't think you'll find anyone really disagreein with you Zaresin but, sadly, I don't really see SE changing it. They'll probably say it's "working as intended". It took me several months to get atma for ONE weapon (since apparently RNGesus utterly hates me with a fiery passion) and I have 3 other jobs I play regularly with Zeniths...so that'll be GREAT. A 5% drop rate for low level content that locks out almost all of the abilities you're used to using with no end in sight? I can't imagine what buffoon thought this was the best way to go about upgrading relics. Hell, even for the book upgrading phase with the Atma, at least you're doing specific tasks with defined goals so I don't even mind those as much. Anyway, I know I'm not saying anything new or exciting either.

tl;dr is that yes, it IS an utterly atrocious system but SE will probably never do anything about it.
