Understood. We have an almost infinite variety of manner in the Anglican church, even in the 1928 BCP churches -- and even in our church we have to harmonize practices with new servers...
The Orthodox are very traditional and keep the manner of the worship very similar. I was fortunate enough to see Orthodox churches in Europe, America and the Far East. They are all Orthodox. The different manner of worship is subtle. For instance, the Japanese tend to kneel and bow down to the ground, but the Orthodox worship should be considered a rite and as such uniform within reason in all churches of that rite, just as Catholic Latin rite is characterized by a certain manner of worship.
What you are describing is any lack of uniformity or rite in the Anglican Church, and that is certainly not the case with the the Church of the East or the West. A rite is a tradition, but not holy; it is not a fad, or fashion.
