I don't know what other attorneys do or do not realize. Yeah, I've met those who think the only proper advocacy is yelling and screaming and picking fights. Fortunately, over a fairly extensive litigation career - both civil and criminal - those have been few and far between. They almost always end up screwing their clients. That was definitely true of the two worst offenders I came across over the course of almost 50 years. One was a jerk miking his clients. The other was downright incompetent.
That's what one of my personal tests comes down to - does this need to be adversarial? Once the answer is, "no," the other question is, does this particular client need someone to speak for them? And even in the second one, the "no" to adversarial still applies. FSDOs have personalities, but I have been involved with several where I have represented clients directly with ASIs without it becoming an attorney-to-attorney battle. In one, my initial contact suggested that the ASI run dealing with me directly by legal counsel. The FAA lawyers never got involved and we resolved it.
