It’s feedback about fighting Grava in a group of bosses, as mentioned in the OP. No other requirements. I have nothing else to add on the matter.
If you don’t have any issues with this boss with melee chars in multiboss environment, maybe you know smth about the game i don’t know or your skill is higher.
I didn’t say that, he is often one of the harder Nem for me, I just don’t see that as a problem as the gap isn’t that large imo, at least not enough to warrant nerfing him further.
