I am a new player and I would hate to see any form of instant levelling service introduced for many reasons....

1) It does not allow me time to experience the many classes and how to best use the skills and abilities of them

2) It does not allow me to experience the tactics needed to do the content

3) I would miss out of years worth of content - just because it may not offer the "best" rewards it does not mean that it is not worthwhile

To me any game is more about the journey than the destination. This game is all about story and to skip the story through a paid levelling service is simply ripping the heart out of it.
