The ability points currently are useless. If your a black mage and NOT putting your points into INT, something is wrong with you..

Now if they wanted to make them more useful, while people will probably bite my head off for saying this, BUT.. instead of having those points be per job/class, be just the 30 points per character, regardless of job/class. So if you put 30 points in INT because you were a black mage, then wanted to play as a warrior, you don't get a new 30 points to put somewhere, they are just placed into INT, that's it.
