YouTube - How To Enter Uldum, Hyjal, Twilight Highlands on 4.0.3a
its ez just watch the video
uldum for this way and most ways you do need a priest...it works at most spots around the entrance into uldum just have him levitate u and just wall walk up the mountain to the other side, then u want to duel him and have him MC u so u can get past the "No Man's Land" Debuff, as soon as u see the debuff leave group immediately
Twilight Highlands u must start at that specific position, its right under mo'grosh Stronghold, its easy to find...some strat is used here just MC past the no mans land debuff and leave party and ur good to go.
For Hyjal go to the entrance at darkwhisper gorge and run a 2nd wow client...log in and it may disconnect or may not, if it doesnt at first just run foward into hyjal past the debuff and ur good to go
thx for reading and good luck
