The increase in numbers of partakers/anointed has left the org with a problem. (I personally suspect also that a huge dispportionate amount of these are females) This is apparent by their use of the term 'genuine' anointed in their more recent articles. They are not able to determine who they think are genuine and who are not. There would be many JWs in the congregations that see partakers and know they couldn't possibly be genuine.
The problem they have is how can they be instructing all JWs to follow a FDS when no-one knows who is a member of that class or not. It becomes unsupportable. So to this day it appears they have put the focus on the Governing Body but other than hinting at the idea that they have 'special talents' or are 'gifted' they have not come up with biblical support for this transition.
Here is an Watchtower (71 12/15) article on the formation of the Governing Body. I have highlighted the more intersting parts.

How did this governing body make its appearance in recent times? Evidently under the direction of Jehovah God and his Son Jesus Christ. According to the facts available, the governing body became associated with the Watch Tower Bible and Tract Society of Pennsylvania. C. T. Russell was patently of that governing body back there in the last quarter of the nineteenth century. Being fully dedicated to God through Christ, he set himself to apply his time, energy, abilities, wealth and influence to defending God’s inspired Word and spreading its message. To that end he began publishing Zion’sWatchTower back there in July of 1879, believing, as he said in its columns, that this had Jehovah’s backing, and hence there would be no solicitation for money. He manifested the qualifications of an overseer as set out in 1 Timothy 3:1-7 and Titus 1:5-9 and accordingly he was requested by the congregation of Christian Bible students at Allegheny to serve as its pastor or spiritual shepherd. Five years later Zion’s Watch Tower Tract Society was incorporated and served as an “agency” to minister spiritual food to thousands of sincere persons seeking to know God and to understand his Word and to come into relationship with him through Christ.
Dedicated, baptized, anointed Christians became associated with that Society at headquarters in Pennsylvania. Whether on the Board of Directors or not, they rendered themselves available for special work of the “faithful and discreet slave” class. They aided in the feeding and directing of the slave class, and thus a governing body made its appearance. This was evidently under the guidance of Jehovah’s invisible active force or holy spirit. Also, under the direction of the Head of the Christian congregation, Jesus Christ the Son of God. True, the members of that governing body were not directly appointed by the Lord Jesus Christ. For that matter, not all the members of the governing body associated with the Jerusalem congregation in the first century were thus directly appointed. How, then, were those “elders” of the Jerusalem congregation who were not numbered among the twelve apostles made members of the governing body? Evidently by appointment of the original twelve apostles, acting under the guidance of Jehovah’s holy spirit.
This is illustrated by the action of those twelve apostles when appointing Stephen and Philip and five other men to take care of certain business of the Jerusalem congregation. (Acts 6:1-8) Also, the apostle Paul pointed out in his remarks to the elders of the Ephesus congregation that the overseers of God’s flock of spiritual sheep were appointed by God’s holy spirit. (Acts 20:28) Thus, too, even though there were no apostles of Christ on hand in the nineteenth century, God’s holy spirit must have been operative toward the formation of the governing body for his anointed remnant of the “faithful and discreet slave” class. The facts speak for themselves. There came on the scene a body of anointed Christians who accepted and undertook the responsibilities of governing the affairs of Jehovah’s dedicated, baptized, anointed people who were following in the footsteps of Jesus Christ and endeavoring to fulfill the work stated in Jesus’ prophecy at Matthew 24:45-47. Facts speak louder than words. The governing body is there. Thankfully Jehovah’s Christian witnesses know and assert that this is no one-man religious organization, but that it has a governing body of spirit-anointed Christians."
