What we really need is more content for all types of players, there should be stuff to do if you are solo, duo, light party, full party, and hopefully someday alliances of 16-24 players!

If there was lots to do, you could choose an activity based on the number of people you could find to play with at that time. You would have something to do duo while you were looking for 2 more members. When you found 2 more you could go do something else.

I waffle back and forth, on one hand I want content that absolutely requires a full party to complete, but I don't like the idea of someone who can only find a light party standing around bored.

Hopefully server transfers/merges will help with the population problem...
