Is there any good reason to not roll a new toon for each class?

Last time I hit C it was displayed a window called Character. As soon as I hover over 'Community' menu at official website I can see 4 options, Character being one of them. IIRC, as soon as we log into the game, a Character Selection screen is displayed and you can see Characters created and saved through Character Creation feature.
Hmmm... What's written above "Allyra Arianos", right next to your avatar image on this very thread?
What is this magic!? Bewitching, isn't it?

I really couldn't care less what you call it, but I think it's the dumbest argument ever to complain about people calling them a term that's existed for about twenty years now.

Is this a Troll? Is the OP seriously questioning if there is good reason to use the job/class system that makes FF unique and versatile compared to other MMOs? Its put in place so you can experience the full content of every class in the game without the silly nonsense of rolling another character.

Unique and versatile, becoming completely useless with lockouts.

yoshi-p himself said that the cross class system is important.. if you have a different job on 8 different characters you have no cross class

You can't lvl cross class abilities on alts?
