A few friends have mentioned that Dragoon and Astro are the two jobs that require the least amount of skill to use and other Jobs such as Black Mage and Scholar require a lot of skill to master correctly.

Do you feel there are jobs that "Noob proof" and require very little skill to use?
If so which roles do you think excel the most? Which do you think tier the lowest?

Do you think Skill matters more than Job?
