what's even the point of asking these questions. i feel like people are asking these questions because similar useless questions have been asked previously giving people more motivation to make such threads. like bitch, if i think i can fc a 7 star map, i'll try when i have the motivation and time. if i don't think i can then fuck that.
if you're thinking about this in terms of pp and ranks as a payout, literally just go find farm maps whether from tillerino or osusearch or looking at people's profiles, or whatever other method there is. personally pp is of secondary concern. I know certain maps will give me decent pp, but i mainly fc them because i like the song and its a sense of satisfaction, although i can't say that nowadays since i don't even play.
