The modern day "great crowd" is Rutherford's finest invention that saved the WTS from certain doom. He called them the "great multitude" in 1935. In the early days, persons that were saved by grace other than being annointed were refered to as the "millions now living will never die". As early as 1918 the "millions now living" refered to the masses of ungodly persons who were considered saved by good works alone. To be saved in 1918 a person did not have to be part of a religious organization. According to currrent WTS doctrine, the great crowd ARE these "millions now living" and the great crowd is exclusively made up of JWs.
This means the ungodly masses can no longer be saved by grace.
So the doctrinal flaw is that the Jws are the only class that can be saved by grace and folks we all know that ain't true
