I posted an idea like this on the XIV beta board. Players loved it, devs didn't care. I'm expecting a similar respons here except with more trolls.
We all now how difficult it is to get things done in this game. Everything requires a group but getting that group together is often times more challenging than the actual fight. The joke I ususaly tell is "This game is like sex. You spend all your time looking for people to do it with, and it's over in 5 minutes." What I am suguesting is an easier way to get groups together.
It starts out with a bulliten board like FF Tactics or My life as a king. Players can post a quest that they need at the cost of items, gil or board points. Responding players can sign up to help or get a similar reward or quest completion as the posting player. Responding players that sign up to help get board points for their own quests, items or gil. Give everyone a certan amount of board points per day and viola, people are now getting stuff done instead of hanging out in Jeuno.
This fixes Juno zone, shout and yell congestion while also fixing the problem of not being able to get things done.
