Preventing others from their objectives from a 100% safe location is not normal. If it is, then please tell me where in all of the warzones i can do this from.
I commend you for capturing this on video and sharing it with us. This allowed us to skip over the "I don't believe you" part of the discussion.
It is clearly an exploit in that it is not working as intended
and will probably be fixed in the future.
If more folks would fraps things like this we would have more productive conversations
As for folks who say "what is the problem"? I agree that the exploit is marginal enough that the exploiter should not be punished unless BW sends him an email saying "don't do that anymore".
