6th Gen What features in Pokemon X and Y would you want in the game ?

I personally Want to have a unified national union room feature which introduces the possibillity of swaping battle stratagies, making friends online and battle anyone that is in that room.
Also I would like to see a co op feature that allows more than one person play in the game at the same time looking for clues and help with the adventure.
