The exp. share in Pokemon X/Y. If you have that item activated, you'll alwways be a couple of levels higher than other trainser. Training has been almost erradicated.

 

This is very true. I didn't use the Exp. share at all during my first and only playthrough to avoid these issues and it made everything a lot more difficult. By the time I reached Elite Four, trainers were always around 5-10 levels above me.
