I want to make a dual blader, and spend some NX on his equips, etc. But, I don't want to do this if the dual blading class is still in a beta testing state, since it's asking me if I want to start off at a certain level (30 ish) and automatically delete itself after the beta is over (if there is one).. So, is this the actual class? Or should I wait to use NX.?
