I was struck by the selection of classes that were chosen for "balancing." I think they were self-balanced. There is reasons again to continue on as a cleric rather than taking a prestige class as soon as you qualify. But balancing in relation to the other classes is silly, given that the cleric and the wizard are two of the most powerful classes in the game. I take it more as a nod back to the old school, with the archetypal classes having a Pathfinder spin on them.
If that's the case, then please say so rather than masking the agenda under the guise of class balance. If that is not the case, then a few other classes need your attention as well (including the sorcerer).
