Imo from what is said in here Duty Finder is to help beginners. People just starting out untill they finish story mode.
"Therefore, I believe the duty finder is a "necessary feature for the players new to the world of MMORPGs."
I would like new players to think "Hey, that was much easier and fun that I thought it would be" after their first party experience."
Similar mentality is used towards pointing blame at the devs rather than the players/community for problems that start from the players/community. They will cling to their wrong perspectives to practically no ends, despite any facts presented. If Yoshi-P wants it to be for beginners (primarily) and for veterans/advanced players to form their own groups, just like the more enjoyable origins of modern-day MMOs, then that's how it's intended. These people won't believe, understand, or follow it though.
So in his own words. It is to help new people. What does the community do? Stamp new players into the ground with harassment etc .
