When you join a new group through the DF there is a good chance you will finish the zone, enjoy yourself, and not be subjected to drama.
When you join a group that is part way through a zone there is a good chance that the experience will make you wish that you hadn't logged on.
This is one of the few cases where "the good of the many" supercedes "the good of the individual". Giving people the option to ignore in-progress groups does more harm than good on average. More so when the DF is set by default to ignore in-progress groups.

Combine the long wait times for replacement tanks and healers with the fact less people play them and you have a recipe for disaster.
