Dude, that guy dropped to mobs MOST EXPENSIVE item on the server (like 8kkk adena at that time or 1-2k euros on black market), so yeah, he is definitely "retard who did this sh1t", he just dealt with it.
Also when he was starting, when he bought eminence bow on his archer he dropped it in same day (or was it next day?) and someone else picked up, but he didnt whine like little crap how unfair it is, because thats the feature of the game.
ps: when i started on this server, i knew this can happen so my motto was -> as long as you gain more from this feature than lose, i am fine with that (i found some items from people dropping from mobs, i dropped some items when people feared me/stunned me to mobs), its very simple.
