Too many epics and legendaries

So i joined multiplayer along a guy, we were both lv 50, he was starting port valbury so we entered. the thing is, every monster dropped an epic or legendary and those who drop unique stuff dropped it constantly(eg every manticore dropped an eye) i died in the run and went to asterkarn road and the same thing happened every monster drops an epic. why tho?

sounds like he modded the game

My best guess is that’s some sort of a hack. Since drops are probably determined server-side I can imagine it being very possible.
