I cant train she now, maybe after event :s There will never be a map which you must use 2BBV. (I seriously doubt it) If there is, just get Isse or Hyuuga to 50 and you will be fine. You can always hold on to the BP and see what you need.

But yeah like I said, I dont think you will ever HAVE to use 2.
