What do you expect/hope Nexon throws in with Big Bang?

I would really, really love to see more Masteria content. Been wanting Versal or Krakia or something since Masteria first came out, though it sounds likely its no longer in development. I quit the game years ago, come back, and they've still barely changed it. But yeah, that has always been my dream for this game. XD
Also get rid of the potential system, or at least just make items drop less frequently. It's taken all the thrill out of finding something.
