About PvM: there is a lot of instances. For solo, for party playing... +- every instance have his worth. You can farm literally every of them, and have you profit from it. They all work almost one in one as on kRO (which NovaRO follow). And you always can find party for them! About WoE/BG/PvP: they all are pretty alive. 4-5 guilds on WoE in one castle provides a lot of action. Classes +- balanced. GMs knows, what they do. But when they not, player base help them with it. And GMs hear players!
