I agree with adding more 4/4 content but not for the reasons you listed. I'm always up for new and exciting content, even with a party limitation on it.

Your issue seems to be that you're in a bad timezone for your server and I'm assuming you're also not in a Linkshell. I would first suggest you try to remedy a few of those issues like find a Linkshell with a number of members active in your timezone that you can play it.

Also SE is releasing the new party search feature so that should make things a little easier.
