Class reform will truly be awesome! I like everything in it. I can't wait to see the rest of it.

5. The Influence of Levels on Actions

As mentioned under 1. Class-specific Actions, upper tier actions will be abolished in favor of scaling the potency of the base action according to level. The effectiveness and MP cost of the action will be dependent upon the level of your current class.
That positively surprised me! It might be my favourite feature of the class reform.
