It's just some suggestions... i had MMORPG's servers too.
1. Website: A new fresh , professional website and simple. 30% of those who visit it give up cuz of design ,why?
Homepage looks like a blogstyle/portal forum design. The website its the first impression that makes for those who visit it. Lots of people are looking for good servers , you need to make that first impression.
2.More Daily's.
3.More quests with some rewards (after 150 gets pretty boring) need more activity after 150.
4.You have to make people stay , make people play , keep them active. Lots of people leave after they lvl up 2-3 chars to 150. You have to focus and ask yourself .. how do i make them stay?
That's the main thing... and there is alot of things that can be done.
In rest is ok.. hope for the best
P.S: What about a Perfect world AAA-quality game engine on a web platform without need to download the game just play it on browser
but i guess it would be laggy
