While I hated X/Y, I felt that this feature allowed people to get the EVs they wanted in their Pokémon in a timely manner, and it could be done as often as you wanted with no cooldown period. That way, you could go through the game as early as you wanted with a fully trained team.
It's certainly a lot easier to get to and use than that thing in Poképelago.
