Skipping to Prince via Netherspace is old news to Explorers... but perhaps the Exploiters missed this sort of thing.
I'll look for a link later, but in the meantime, here's a link to my "skip to Maiden" video, which shows the fastest way to escape Karazhan (least amount of mob clearing).

*edit: I just found several threads on OwnedCore listing this shortcut to Prince... however they're all so old (2009+) that the videos in all threads have long expired! That's how old this exploit is...congrats on finding it for yourself though and thanks for trying to contribute.
