As a veteran RO player, it's good to have a stable server like Nova nowadays. Although Gravity by itself made some class unbalance changes with the past episodes, Nova still requires people to group up to do end game content. Don't have many issues with the community, and the GMs responsible for events seems great people to chat with. It's hard to control the mudflation, and that's even harder considering that Nova is online for almost 5 year, but here this is not that game breaking.
