I agree with many of the above posters:
1. Non-profit
I love the current model where there is transparency of cost, and the game is non-profit. It feels like a true community effort to keep this game going. I believe this model could be sustained indefinitely. A reasonable license fee to NCSoft could be added to the current cost load.
2. Transparency
You've done a great job with this. Please don't stop.
3. Tune-up then expand
Continue to fix the bugs and and address balance issues for some of the older powersets before attempting new content. Refresh the UI. Content for Kallisti.
After that, I would love an expansion of the incarnate story line and an invasion of the Rikti homeworld sounds great.
