The other good suggestion i dont see mentioned is the Party Finder, so i guess ill offer that. Party Finder is an alternative tool to the Duty Finder youve primarily used to this point. Using the tool, you designate the content you want to run(like "Striking Tree(Hard)" for instance) and it creates an open party that anyone can join to help you clear that content. Other people who need the same content can join, along with anyone who wants to help. And believe me, there are people who would join to help. The game gives bonuses for helping new players complete instances for the first time, not to mention those who might join for a chance at the drops from a fight, or those who just happen to like a certain fight and run it whenever they can.
