Have you guys played normal exps after DON? After I got 9999 I went back to nornal exps and holy shit you're so OP. You can solo(3p scaling) bosses at lvl 4/5 around the same time it takes 3p at lvl 9/10. You can also tank so many hits, it's absurd.
I was never a great player or anything but DON unironically made me into one.
