Stability and Availability is fine. The community are friendly, they always help you whenever you need. There aren't many events available out there though. Game Masters are friendly, easy to contact and get along with, and they also help you when you need it. So far, the economy, it has a low competition, which means, nobody's so rich, and newbies can keep up. On WoE, there are only 1 castle, with 2 guilds fighting for it. It's understandable though. And for class balanced, it's just balanced.

Stability, well, about that, it's hosted on a good web host and I don't lag that much. Whenever I play, its always up (rarely crashes). The community is quite friendly, you ask, they answer in a good way (though we can't avoid trollers). The GMs are really friendly and helpful enough (uh, I think) especially GM Howl <3. Most of the time, GMs are available through different mediums. The economy and job classes are balanced. I haven't joined WoE so dunno about Guild Competition, but it looks fair.
