At the end of the month a lot of people will be trying dancer(and gunblade) for the first time, and no one will be good at it yet(some will learn fast, some im sure will never get the hang of it). So just farming up some poetics(for gear) and putting the story in a good place to jump in with your new class is probly a great idea. As for the classes being changed, everything is getting tweaked. Six of the DPS will be "mostly the same", the other 3 being some degree of rebuilt. Tanking and healing are getting general overhauls, which will of course effect all 6 classes. Role actions will be changing again for everyone. And of course, some new skills in the 71-80 range all around. That might be one of the topics that comes up in the live letter this week.
