You need to calm down.
My post wasn't about personal attacks or "harm," so I have no clue what you're talking about. You also seemed to have missed the point of my post with the bolded text above - the very crux of the problem with the referenced posts is that you can't ignore them, as they, by their nature, derail substantive discussion and crowd out those who want to have legitimate conversations.
Drive-by posting wouldn't be so discouraged if not for the fact that it's hard to ignore because it hampers relevant dialogue. I'll be honest, I'm a little baffled that this explanation was necessary.
To stay on topic: I was personally curious about the effect the rope launcher would have on regular free-roaming parkour. Glad to hear it may actually be a useful addition.
