Interested in this.

[i]"There're 3 common jobs: Warrior, Magician, Archer. Everybody can use magic, though non-magicians would usually increase their killing power with the use of MP, instead of using the attribute due to higher efficency"[/i]

There are two ways one could take this. Either it's actually just better to raise MP, or raising MP is the lazy route and if you actually spend all the time to raise your casting stat you end up being able to blow through comparatively weak shields and easily block comparatively weak spells, even if you can cast less of them. Which is it, if you don't mind my asking?
