Duty Finder goes to show how intelligent Experience Point parties really were.

Duty Finder doesn't come up with the wacky party set ups that work, only the most traditional setup.

Perhaps Duty Finder should have the option to seek a group for a variety of party set ups

1. Traditional (as current)
2. Classes only
3. Jobs only
4. Free for all

I've seen posts on reddit where parties are having their carbuncle tank dungeons so I don't see why not basically.
