Current state of KMST JOB Balance

I'd rather they add a series of quests that can be done every 10 levels in 4th job (or even earlier jobs also). These quests would (assuming you've maxed the correct skill) give you a mastered version of the skill in question (a point would be automatically added into the skill also, heck they could even add a sub-book that contains mastered skill variants of the original).

These changes could be explained away as the job instructors not wanting to divulge the extremely powerful form to everyone/ the character not being ready for the power of the ability / a new way to increase the power of the skill being found. Then every time they want to increase the power of a skill they could add another quest chain that would give a 2nd level to the skill, or have the old skill removed and replaced by the new, stronger one (this way paladin's combat orders would still benefit those who have mastered versions of skills).

Basically I'd rather they add an in-game reason for the power increase / skill change than just modify the skills themselves and incorporate them into the game with no background. Hell, even having people be automatically warped to their job instructor with an explanation of the new skill changes and why they occurred (the black mage, yada yada yada, new skills to combat him...)
