Do you find that using both of these is redundant? The purpose of both states is to prevent the target from acting, and since this is such a powerful effect, the duration is usually limited to about 2 turns. To me, there is an obvious thematic difference in these skills (you'd get stunned by the giant ogre's hammer. you'd get paralyzed by the lich's dark magic spell) but I'm not sure there's a large enough functional difference to justify having both. For people who do use both, how do you differentiate the two states while still maintaining good balance and design?
