When you call me retarded because you don't understand, or can't/haven't communicated a point well, don't expect me to be pleasant. While I may or may not be narrow minded, I can only come up with about 4 or 5 situations where KS is possible (or at least where I've done it), and none where it's unavoidable.
As Hitech has said many times (perhaps you haven't seen all of the threads), the shooter is at all times responsible for knowing what's happening around him. The friendly who crosses through your bullet path isn't at fault (although he's arguably also displaying bad SA); you can't shoot him unless you pull the trigger. A lot of people have suggested a lot of ideas over the years, and none that I've seen or can imagine accomplish the same things. For it to work in the MA, it's got to deter fragging teammates, remove the extra bad guy from a fight, and/or not punish the innocent while punishing the party at fault.
I'd like to see film of "those above" abusing the KS setup. I think, and I won't bother putting this mildly, that you're lying in an attempt to bolster your position. While you cite "internet realities", you need to consider also that those same realities apply to everyone in the arena. Using the justification that KS needs to be changed or removed because you might possibly shoot someone because they're warping just doesn't float.
