G43 seems to have a loophole.

If you are in contact with a defense, but your bumpers are not breaking the plane of the outer works (for instance, you have grabbed the top of the drawbridge and are pulling it down by backing away from the outer works), are you still protected? The way the rules are now written I don't think so.

That means that once a robot begins opening the category C defenses, as soon as its bumper clears the plane of the outer works, you can ram them away from the defense.

I expect that to be rectified in a team update.
