Why is the exp share still broken in Omega Ruby and Alpha Sapphire?

I began playing Alpha Sapphire today and have just gotten the idiotic exp share. Prior to X and Y the exp share was a item that you could give to a single pokemon. When another pokemon battled the pokemon that battled and the pokemon holding the exp share would get half of the full experience each. It was a nice item for leveling up weak pokemon and pokemon you couldn't use in the area you where in. But i wasn't broken since you gained no extra expierence by using it. Unfortunaly the X and Y exp share is a key item that shares the battling pokemons exp to the rest of the team. Shares isn't the rigth word. It doesn't divide the exp and gives all pokemon the full exp points. If you have six pokemon you will get six times as much exp as if you had one pokemon if the exp share are on. This is so broken and makes your pokemon level up super fast. This makes the game much easier then it was intended becuase you will gain ridicoulosy high levels and steamroll any challenge down. I know that you can turn of the exp share. And i do that and did that in X and Y. But that's just me, i bet 97% of all players won't and will make the game super easy. Pokemon games has always been easy but they were still hard enough to make you try and feel in danger sometimes. Why did Gamefreak suddenly implement such a difficulty lowering feature? Pokemon Black and White 2 , the game rigth before had a difficulty highering feature. Gamefreak also has realized that pokemon has a big skilled adult community whit how extra much they care about the metagame nowadays. They know that the players isn't just dumb little kids. So why do they make the exp share so broken? I am so pissed that the perfect Alpha Sapphire will be so much worse for most players becuase of a single stupid and paltry item they should have fixed at this point.>:(
