Generally, classes that have a multitude of lagging techniques (bash, trip, etc) are also ones that do very well in a mutual command denial situation. Warriors, assassins, rangers, etc. Mages, obviously, tend to have abilities to *prevent* command denial, trying to avoid these situations. Of course, some of the most enjoyable wins are those where the other player is convinced of his superiority, tries to bash you down, and you end up the better in the situation.
