How would you feel about the idea of a Calculator job in FFXIV?

I do not expect to see Calculator (or Arithmetician) as a job class any time soon. Or at all. I do think it's fun to think about it though and I am very interested if any of the Dev's even gave it a thought at all and would find the response very entertaining. Yoshi P if you are reading this please respond!

addendum: I realize the chances of Yoshi P replying are slim to none, but it's worth a shot.

For those of you who are unaware of what a calculator is: A job that existed in Final fantasy tactics where you form an equation as a method of targeting spells that does not require MP or charge time. Calculator spell pool draws from Black,White,Time mages, Oracle the character itself has learned. Calculator is often thought of to be highly over powered.
