This is a redone post about powerlvling from 49-52 in ST. However you can actually start doing this at lvl 35 and get WAY more xp.
In the video we don't show it, but you can actually pull the troll boss that heals over to zolo and go on forever or untill the pally's durability holds out.
Take in mind my rogue in the video is lvl 50 and is therefore recieving much less xp than a lvl 40. We ended up averaging 140k xp per hour when we finished.

I can add filefront stream if needed or music, but as of right now theres your streaming vid
Just recently I've sucessfully done it with a resto shaman instead of a pally I can link a vid if anyone wants to see.
