Seems they removed the ability to teleport in. Before anyone starts in with the "it is behind a locked door for a reason" or "oh it will make it special again" you can't tell me this was done for any reason at all other than throttling the economy. First they capped bonuses at 30, now you have to bend over backwards to get back in.
This will hurt the casuals, people who have a job or family or can't be on for very long at a time. They can't sit around camping a key, or a person with a key. As for buying the keys, well, When I bought mine earlier in the week on the auction house they were already going for 7k, as of right now there are no keys at all - I bet they sky rocket so you would need to be a farmer there to be able to afford a key to get IN there.
ALL OF THAT ASIDE, a bit of warning would have been nice, I would have stayed camped there instead of porting to my house when I logged out earlier.
