The doctrine changing is still not a big issue for me per se. I would be much more bothered if they realized that one of their teachings was against the Bible yet they continued teaching it.
How about if the 'changing doctrine' including going back to an old/previous position, and calling it "new light"?
Organ Transplants...
-1961 = Conscience choice.
[Watchtower August 1, 1961 'Question from Readers']
-1967 = Cannibalistic.
[Watchtower November 15, 1967 ‘Questions from Readers’]
-1980 = Conscience choice.
[Watchtower March 15, 1980, page 31]
So, the light in 1967 becomes brighter than it was in 1961 and Jehovah's Witnesses are taught Organ Transplants are now cannibalistic. However, 13 years later the light becomes brighter again and in 1980, Jehovah's Witnesses are taught Organ Transplants are no longer cannibalistic but a conscience choice, which is actually returning back to their previous stance in 1961.
Resurrection of the Men of Sodom...
-1879 = Yes.
[Watchtower July 1879, page 8]
-1952 = No.
[Watchtower June 1, 1952, page 338]
-1965 = Yes.
[Watchtower August 1, 1965, page 479]
-1982 = Yes.
[Live Forever Paradise Earth 1982 edition, page 179]
-1988 = No.
[Watchtower June 1, 1988 page 31]
-1988 = Yes.
[Insight on the Scriptures Volume 2, page 985]
-1989 = No.
[Our Kingdom Ministry, December 1989, page 7]
-1989 = No.
[Live Forever Paradise Earth 1989 edition, page 179]
The number of times the Watchtower Society's teaching changes concerning the resurrection of the Men of Sodom is staggering. The above does not read as divine direction, "brighter light" coming from Jehovah, just an organization haphazardly guessing and arbitrarily deciding what to teach.
Superior Authorities (Romans 13:1)...
-1886 = Worldly Governments or Authorities
[Studies in the Scriptures Series I - The Divine Plan of the Ages (1886 edition) page 250]
-1916 = Worldly Governments or Authorities
[Studies in the Scriptures Series I - The Divine Plan of the Ages (1916 edition) page 266]
-1929 = Jehovah God and Jesus Christ
[Watchtower June 1 and June 15, 1929]
-1950 = Jehovah God and Jesus Christ
[This Means Everlasting Life (1950) page 197]
-1962 = Worldly Governments or Authorities
[Babylon the Great Has Fallen! God's Kingdom Rules! (1962) page 548]
-1990 = Worldly Governments or Authorities
[Watchtower November 1, 1990, page 11]
So the "Superior Authorities" were Worldly Governments or Authorities from 1886-1929. From 1929-1962 new light flashed forth making the "Superior Authorities" Jehovah and Jesus. Then finally more new light flashing forth brought the teachings of “Super Authorities” to Jehovah's Witnesses from 1962 onward back to the original teaching of 1886.
This Generation (Mathew 24:34)...
-1927 = The Anointed
[Watchtower February 15, 1927 page 62]
-1942 = Anyone alive to see 1914
[Watchtower July 1, 1942 page 204]
-1995 = Wicked People alive today
[Watchtower November 1, 1995 page 19]
-2008 = The Anointed
[Watchtower February 15, 2008 page 24]
From an analysis of the Watchtower Society’s teaching concerning "This Generation" as recorded in Matthew, it was first ‘correct’ in 1927. But brighter light caused it to become an incorrect teaching of a couple of different things over the course of 81 years, only to return back to the original ‘correct’ 1927 teaching.
The above "changing doctrine" are a HUGE part of what made me leave the Watchtower Society controlled Jehovah's Witneeses.
