Right now the server is just up for a pre open beta, to make sure leveling ans things like that work. They want to reset it when they go into open beta. Open beta will have a large number of the bugs we encounter now fixed. So the best way to put it is the game isn't good enough to play quite yet, but its enough to stress test a server and collect bug info.
Yea, the Fighter master class goes to the martial artist after reaching level 30 and getting to korins tower. Its going to be the staff weapon.
