There is only one thing worse then exploiters and campers, and thats item stealers!
These low life motherfuc*er are the once who join your group for some team missions then ninja loots all chests and ultimately steals the pickup item thinking you wouldnt notice.
The sad part is that the pickup item is usually some worthless pice of garbage and the real mission reward is something you really need. The trend seems to be that the underequipped and usually the lowest lvl in the team is the one who cant resist stealing the item even tough he has been mooching xp all day.
This is just a game but seriously, if where in say a lan party playing AO and there was a guy there who stole my mission item i would without a doubt punch his f0cking teeth out.
