Should there be a leveling system?

There is a public leveling system available that has a lot of features based around player and pet level. You can read up on the features here but here are the features that it comes with. There may have to be changes (small or large) to make it work here. I think it would give players something to aim for such as having a 0 slot mount at player level 60 for example. Please vote and let me know your thoughts in this thread.
