1) There's no cross-class system anymore. And for good reason.

3) Not sure where 'level 32' was pulled out of.

2) 'Leveling to get new abilities' is not a challenge. It's tedious and turns people off. (Unless you actually think forcing people to level a job they don't like in order to play their main job is fun and challenging....which is sounds like you do)

Go google for a little bit and come back. I could give you the information, but you should work for what you want.
