I would agree with some of this. But I feel from my experience and in talking to others, when the WAS leaves or files for D, they have been unhappy or wanted something to change for a long time. Could we have done a better job of paying attention and being actively engaged in the R? Could they have done a better job of expressing their frustration or unhappiness? The answer to both, is yes.
The irony is, for me anyway and others who have expressed similar sentiment, is we much better understand ourselves and our areas we can improve in and understand more about the dynamic.
