I can tell you for sure that there will be rebates in the near future, just as any other event. Most likely when the 'Refine Rebate' ends. I just restarted on a new server and I'm currently level 55. Is there a certain level you have to unlock this feature? Also, is there a certain thing I need to click to access it? I went to Mt. Myoboku but I got no introduction or anything.
