I'm a dretch player and seem to be best at it than anything else. I think that maybe maneuverability of the dretch gives it that edge. Obviously the downside is that you can't chase anyone, because you are an easy prey. But, it's free and in vanilla you really don't do much (if any) damage, to team mates. I just have to watch the feed rate because it might end up hurting the team in the long run.
