I know exactly how this works...1) Any profession can do it, just that NTs are faster because of AoE 2) I have reported it also 3) I was accidently a part of a team that was doing this (when the first mob dropped, I left because I knew it wasn't right) 3) I have been told that it is not considered an exploit, but that doesn't mean that I don't think it is one.
Its this simple, if FC is saying it isn't an expliot, use it until they tell you it is...just make sure you save copies of people saying that it isn't an exploit as your defense. Is that right? No, but it is the only choice that we have been left with.
