good place to lvlFollow

as you can see from the subject i dont know of a good place to lvl wondering if anyone knows where a good place where a lvl 13 can lvl with his friendswho are lvl 40 and up and where they wont get bored and kill everyone and where i wont die

That place doesn't exist. But having your friends run you through instances multiple times, once you hit the right level for the given instance, will level you relatively quickly, keep your friends from leveling and gear you up quite nicely.
