I believe we are both on the same page, here. I myself never said parsers should be banned, and I don't believe that they should be. It's all in the understanding that parser numbers are raw data, and that alone, and not in any complete to boot. Those who fail, or worse, refuse to recognize that fact are the ones that give the very idea of parsing a bad name.
Used properly as a tool to improve one's *own* performance, and to develop tactics for a given raid scenario, they have great utility. It is when one aims one's parser at another player where the problems really start beginning...
