Custom content - how much is too much?

[Ivory]

Cap level max at 39....and the game shall forever be exciting and challenging. Even 5 years later people will still be struggling to achieve a new piece of gear...instead of finding themselves so bored of stomping all content in the game that they begin to challenge each other to who can show off best by soloing raid content like dragons.

((And if you want, you could decrease exp gain to make up for the loss of levels)).
