It's a question of ethics, in a way, as well. It's VERY poor for Blizz to say "We know that we've created a terrible monster. We acknowledge that this is causing a BIG problem for a large number of players. We know perfectly well that this behaviour is detrimental to the enjoyment of other players in the game. We also know that this is stoppable/preventable. We don't care that you're being made so you cannot enjoy your gaming experience, despite the fact that you're paying us to play. We'll just sit here and let this other group over here, who clearly pose a severely unfair advantage over you, enjoy THEIR gaming time instead because we fell you're just a bunch of babies who can't grow balls."
