You know, I like this idea. But to expand on it a little, you could have a "Learning" Duty Finder for people who haven't done something yet. Or even better, a check box to indicate you're a first-timer. That way inexperienced players get grouped together in order to learn something together or just to practice to get better. If you're an experienced player willing to help new folks out, you could check this as well. People who want to speed run will stay out of this because they know they'll be slowed down by "Noobs", and the kinds of people who are willing to help new folks out will be less likely to compete against low-level gear for the sole purpose of desynthing or passing it off for Grand Company seals.
