I actually like the fact that you have a lot of options in this game. It is not perfect but you can choose to go leisurely or go crazy grind level at end game. You can do minimal interaction with people or heavily grouping with your LS + FC people. It is however you want to make of it and the game is giving you that options. People who are very social can easily make new friends since most of the later level contents are much bearable to do with friends. The antisocial can do their crafting and gathering without dealing with others ;P
