I honestly liked the Dream World part of Game Sync on my Pokemon Black game...It was very fun, and the music was so relaxing. I wish they'd have put it in X and Y...
I hope Nintendo would make an update about adding that feature.
EDIT: Also, I read that the Kalos region Pokemon can learn Abilities from the Dream World itself...so, do you want it to come back?
