You can't though, you think it's that long to punish people who ditch a group, but what about the people who leave because the group CAN'T down the content? People who joined and just don't have what it takes, gear or skill wise to clear it? Now everyone has to wait for the timer to end, or one guy leaves and takes your 3 hour punishment. There's a reason it's not overly long.

The first person to leave a full DF group gets a 15 minute timer, this also resets when you change zones and a few other things, so could be longer than 15 if they don't know this.
