I'm not sure if this is being done already, but I feel like mentioning it. If you're a WHM and then level up a SCH, or vice versa, the attribute points you use for each should somehow give you a benefit for each job too. Ex: if you're primarily a SCH and invested some points into INT, then when you level a WHM you should get some sort of attack bonus for having a past job of SCH. Or if as a WHM you invested in Mind, then as a SCH you could have a healing bonus for having been a WHM. This can work on other classes and jobs too.
