I was in Hightown farming uniques as usual, there was this Daredevil fully geared just standing there waiting for me to defeat the boss which was pretty slow because I didn't have much gear. When the boss was about to die he just hits the boss once and gets loot from it.
If you are going to Hightown for loot, the least you can do is atleast help defeat the boss and not just stand there, leeching off of other guys work.
Hopefully you recognize yourself to not be this kind of a player.
