Is there even such thing as a casual crafter?

I'd like to be a casual crafter but the fact that I have to get all classes to 50 to even start has been what's stopped me doing it for the past 2 years...

Seems to me they should rethink the cross-role skills a little better, and make them skills that are only essential for higher difficulty crafts.
These 'higher difficulty crafts' could prohibit the use of common skills like Prudent Touch, if that's what would be most effective at making them so difficult...
