I have seen twice the use of some kind of fast travel in EotM. Many here have posted their claims about hack uses. Last time a minute ago our commander suspected a hack in the chat (good well known commander).
While Anet could collect better metrics and analyse them for hacks, it also would be possible to give us the metrics via the API. Say, 24 hour delay in giving out the metrics so that the metrics would not be misused. Player identity could be hidden, but in a way that we may still report the person (e.g. IDs which change time-to-time, or at map change, or at wp use).
