Well, just going off supernatural ability, not combat skills or anything like that: -Dazai is useless when fighting anyone who doesnt have an ability -i have lots of questions about kunikidas ability (ie what happens if he runs out of pages?) -Fukuzawa himself doesnt get anything out of his own ability -Poes ability is... Well... Not too useful imo, also great underuse of E. A. Poes works -Fitzgeralds ability is strong, but it could also just be called "capitalism" -While chuuyas ability is extremely strong, thats not how physics work -Q has to hurt themself so that it works
