An IP can be sniffed easier on Bungie’s P2P.

That's fine. But in my experience I can't really tell you if I've even encountered a cheater. Remember that most PVP problems are caused by the P2P connections not due to cheating. But if you can find solid evidence other than anecdotal evidence then your assumptions would have any validity. Otherwise they're just individual gripes about unique circumstances that don't affect the majority of the population
