It's a request, yes, but as I am currently not subscribed to WoW, I cannot test this myself. Here goes:
I just recently watched a video of someone getting out of Deepholm, and it came to me that since Deepholm, the Maelstrom, Kezan and Lost Isles are all on separate servers from the rest of Azeroth, maybe they're all actually on the same server. (just like Outland, Ghostlands, Eversong Woods etc...)
Basically what I'm requesting is that someone glitches themselves out of Deepholm and then tries otherworld to bypass the blue walls surrounding it. What that might accomplish is that maybe you'll get to Kezan or Lost Isles.
