Agile was supposed to ease up on process and make teams adapt to changing requirements. It wasn't supposed to use up >30% of your working time just to service the methodology, but that's what it ends up doing when you get in the Agile Evangelists.

Well, I've worked in a (non-agile) environment where the methodology ate up way more than 30% of our working time. If an Agile Evangelist could have gotten us to 30%, most of us would have been ecstatic. (It wouldn't happen, though - we were FDA regulated as a medical device manufacturer, which imposed huge overhead requirements.)
