So you guys remember how back in the day if you were a mage you could blink through the portal in deadmines, run and slowfall to see the content blizz was hiding? There's a vid somewhere just got to find it again. Anyways, they fixed, from what i can tell the deadmines blink glitch, so you can not do it anymore. Though I was just in stratholme, and blinked through the instance portal, and hopped out on the other side, mounted up and started running around plaguelands! Basically, i think this could be useful for an 85 mage that can blink through and get on their flying mount, and explore from there. Wasn't really useful for me since my main isn't a mage, though it would be fun to see what is around.
Let me know if you guys see anything neat! =P
P.S. Did this 3 times blinking through no issues.
