OP describes how a hybrid is in this game vs a pure bred and that is exactly how hybrids are supposed to work. You surrender high-end #'s with more versatility in what you can do move to move. I've found I like the versatility over the best possible #'s most of the time. Why? Because for me many times in battle the best move isn't your pure classes move, but something else. If Hybrids were just as strong plus the versatility, there would be no use for pure breds. Not sure what the issue is here?

For example something simple like everyone having the Teleport spell is highly tactical and powerful with simply a single point. The penalties doesn't make a skill useless if you can't get to the pre-req.
