I agree Justin, but the potential for *unintentional* damage is still very much there, that's a big part of why you trained. I'm good with MA: S&T (Wrestling) as the source of the skill bonus, but I can't say I'm all that happy with the results it generates. Yes, failure should be failure, unqualified success should equal *control* of your opponent, possibly with major damage, most likely with little or none. But part of me also wants a near success or a barely successful result to yield damage *but not* control.
Achieving this would also make it much more useful to the Channeling Healer who wants to make a tumbling maneuver *through an ongoing melee* and hopes to come out with a saveable patient on the other side. If the MA roll is successful, the tumbling maneuver continues with the patient as part of the maneuver. It would also make it much more useful to the GM facing that, as he has an answer to, "Okay but what if the Healer gets stepped on on the way through? Or what if the Healer only *barely* succeeds as he rolls through? Does that mean he grabs a wrist as he goes by and his own motion dislocates his patients' shoulder?"
