If you are referring to the random teleport you are correct, if you have been playing for a long time the random teleport is pretty much useless because you can easily afford an advanced teleport. However, for new players a random teleport could be useful. The cost for a random teleport is less, than the cost of the advance teleport. When you are small, gold is hard to come by, and being able to teleport away from a busy area for cheaper can save you some gold or alliance points that you can spend on something else.
