Per the OP, Tantum Ergo gave a good answer. Likewise the Orthodox don’t want a Pope who meddles with individual bishops–over the course of centuries, especially post-schism, Popes exercised more and more of their authority over individual bishops and diocese–the allowance of individual bishops and local synods to exercise more autonomy is keeping more with the practice of the early Church, which the Orthodox prefer.
As for the problem you speak of, it is nothing new. If you look at some of the letters of St. Basil the Great, he is surrounded by horrible bishops–as he says, the more heretical and man-pleasing you are, the more likely you will become a bishop in his day. He wrote to Pope St. Damasus I to do something about it, and the Pope basically ignored him–St. Basil then writes a private letter to a friend expressing his disappointment, not unlike the feelings expressed in the OP.
