I just started watching jojo like 2 weeks ago i'm on part 3 now i dont remember what episode all i know without looking is that they just defeated some sort of witch girl or whatever that was hiding inside of another girl that placed its stand inside of joeseph's arm in the form of a tumor somehow and i'm wondering why hamon just doesnt exist anymore. i mean i read some stuff about it and i heard that its because it would be nearly impossible to come up with a backstory for a bunch of hamon users and that stands were alot more diverse but i feel like hamon should still have a use in the show or should atleast be mentioned at all.
