I'm confused by this. There is NO process. They pick whoever they think fits best and that's it.
Remember, there should be no expectation of promotion in Bethel. If you have, you also have an "attitude" problem, which would disqualify you. There is no seniority that will further you in the queue to be in those GB wednesday meetings. There's no amount of years or service or skills that gets you there.
So no, I don't think this shows any problems or will cause any problems in the leadership. Some might get disappointed and that's all.
