Power leveling should be legal a lot of people have stayed and played because of it. Leveling is hard and leaves people starving for tp power leveling helps stopping that and it also gives people a chance to roll a new class so they can play that instead of a class they learned to hate so they quit. It's only right it has helped a lot of people.
Do you have any original suggestions or are they all regurgitations of old suggestions? If you farm tp, like you stated in a previous thread, you will not be as starved. Several of us, who have been playing for a very long time now have excess tp. As for power leveling, it is still possible. Just not the way it was before.
