If he forces a charge from a non wounded buff and the client knows and wants this then it is as humain as any other form of hunting.

I'm not sure about this gut shooting theory, but if thats the case he's a pure ass. It is the hunter responsibility to put the game down as quickly and humanly as possible, period. Any divergence from this and you are not a sportsmen.

PS I can think of no insult to a hunter lower then being called a non sportsmen.
