That would be the point of it. Just like if you want more HP... to have more HP you have to give up some other stats, so if you want more drops and exp you have to give up some other stats for it.Very good thought, to get those bonuses you would have to sacrifice a lot though!
The purpose of this suggestion is to make charm an useful stat that worths the stat points.
