With zero Holy Spirit leading the WTBTS, you will get a mixed bag of COs. Like BOEs, you have good and bad individuals.
Ultimately, it's all more bad than good, because a few nice personalities will never offset the pseudo-spiritual corporate structure of the WTBTS. The best case scenario is that you get a decent guy who visits every 6 months. Visiting one week, every 6 months, is not enough to make any real impact. Then if the CO is nice, he's moved after a couple of years.
The WTBTS doesn't seem to want any real connection to be made between the sheeple and the CO. They just want the sheeple to have a slightly warm and fuzzy feeling every so often, but they don't want human connections made.
Just imagine if a nice CO could actually be trusted with real feelings about the corruption in the WTBTS. The WTBTS went to great lengths to go corporate, they do not want to go back to the days of independent congregations.
