Currently now I have just ran into a Chest farmer in Wanderer's Palace and this person has full DL, relic weapon, and have access to Binding Coil due to his Allagan Shield being proof.
I will not display his name but I can see this being a serious Harassment issue if more people start to support this kind of abuse.
This issue is that the chest farmer will run to open all chest before the first boss of the dungeon and refuse to leave until one of the group leaves so he or she will not deal with the 15 minute wait time so he or she can continue Farming Craft items from Wanderer's Palace by opening only the first bunch of chest before the first boss.
The person will continue this harassment on every group he or she joins until banned or restricted from joining dungeons.
( I already reported him or her but this issue I can see becoming a major one if people continue to support this kind of activity because it basically harasses people who are joining the dungeon run for the purpose of completing the dungeon. There are also constantly new players joining the game and place like Wanderer's palace is a place where they will go to start building for AK run and gather some tomes for their DL.)
