Worst part about these, is that they don't even try to address the huge discrepancy between casters and non casters. It doesn't really matter that the druid, cleric or wizard have dead levels, because they have spells. Even if they did not have any other class features, with spells alone they'd already be leaps and bounds above the mundanes.
Worst of all, it doesn't even try to address the monk because he has no dead levels. Like that in and of itself means squat when these abilities are complete ****.
