A party member has withdrawn...

[DeadRiser]

Multiple ways to fix this.

People who spam withdraw more than 4 times within a certain amount of time get a 30 min lockout timer just like people who abandon.
People who leave the dungeon early because they get their loot on first/second/third boss, put all the chests at the end of the run.

It gets very frustrating queuing up just to see people spamming withdraw because they would rather not do the dungeon and make everyone else have a miserable time waiting to get in. Even queuing up as a full party for CT, we had to wait for 20 minutes because so many people were spamming withdraw. Don't get me started on the people that leave as soon as they get their drop. Loot should be awarded after the dungeon.

People would go even more crazy to just join the last boss.... UNLESS!!! Tadatada!!! You make the players able to roll only if they were there for the kill of the corresponding boss for each chest.
