One of my biggest pushes in the expansion was to hit 71 as soon as possible so that I could get to Dalaran. There's a simple quest that mages can do at 71, and then you learn how to teleport to Dalaran. I was also under the impression that the portal to Dalaran could be learned at the same time (which didn't make sense, but I believed it, and I think it was that way in beta). The reason for this was simply so I could port all my guildies to Dalaran way before they hit 74.
Well... the portal can't be learned until 74. So, we pulled off what we call the Ghetto Portal. (Figured it out with the help of a certain priest in our guild.) I teleported to Dalaran, queued my party for a battleground, and then once entered, they went afk and were transported back to Dalaran. There's a small issue as far as the level range goes. Everyone that was 71 or higher, was no issue. I did it once with some 70's though, and they didn't get queued in everything I did. I queued in both WSG and Strands of the Ancients (Sota?). They got 1 and not the other. (Don't recall which one atm.
So, there you have it. And now anyone that's set their hearthstone there can do the same trick. Oh, and once you're there, you can also do the attunement quest that starts up in Dalaran (by the floating triangle thing) and get attuned yourself. So, level 74? Bah. That's so not even right. heh.
