Honestly, as first class I would recommend playing it by hand. You won't really have much idea of how the game is played if you don't level at least one class by hand.
That being said, Fatebot is how I level my other classes. Just move your character to a zone that has FATEs appropriate to your level and turn it on. It'll do the rest for you. Move to a new zone once you out level that zone.
If you would rather grind there's a 1-50 grinding profile for order bot under profiles.
