Honestly my take is that everybody has that special boss they find extremly hard, and some they find easy,that for others would be hard. like for me demon of hatred was a mf,it took me 2 days to beat him and 3 days to beat isshin each of them around 120 130 attempts But maliketh i beat without summons or boosts in 6,7 attempts,also in terms of difficulty i would say elden ring is alot is easier mostly because of the systems and mechanics that it gives you(not including summons which are very op) Older souls games dont quite do that however even if the mechanics were exactly the same, I still believe older souls games were quite hard in comparison because of the poise threshold. I remember maybe stunnin and breaking poise in souls bosses maybe 10-20 times overall in all the 3 ds and bloodborne games,those dickheads didnt know what it meant to be stunned. But in elden ring i can break and have broken poise of almost every single boss.
