Actually every time I've said you've done something impossible I've asked for a ruling that has had you have to change your post. 

1st - Knock a sword all the way across your body, result, hits body.
2nd - Lift massive spear and deliver a tendon cutting sweep, result, Judge rules it would barely have the momentum to graze.
3rd - Fully extend heavy shield faster than a longsword chop, result, sword hits arm.

So far you've actually managed to do nothing that I said you wouldn't physically be able to do, because those things were irrational.

I'm not arguing about the sword because I think it's a deadly attack, I'm arguing because I think it's logically impossible and that ruins my immersion, and I think not confronting you about the position of your shield now will just cause more trouble for what I had planned to do next.
