Hehe, that's because people running on walls is perfectly plausible in the real world. And no matter how much bone density increases in orks, it would take a force of immense magnitude to lift a body off it's feet. Even then, my biggest issue was that the shot came from above, not straight on so to me it just didn't make any sense that he would or even could go flying anywhere.
And honestly, if the game doesn't make any sense I will challenge it, because that makes it a little hard to play. That being said, I've said my piece, so let's just move on.
(And JackVII, I am in fact running my own game; I joined this one because I felt like playing in one too; that doesn't mean I should expect this to turn into Matrixrun all of a sudden in my opinion; the world of Shadowrun has always been fairly grounded in reality in most areas, again in my opinion, so when that is changed on the fly I take exception, because my expectations are suddenly thrown out of whack. That is all. But I agree, enough of this and back to the thugs)
