Right, I like Mortred because she's ALL of the debuff you need in one character, instead of spreading it around in one or two spells from each. She's got everything you need to completely disable an opponent, so you can feel free to go crazy with hard autoattacking teammates like Beelzebub. I feel like I save a lot on healing and defense by having Mortred force a "miss" or a "dizzy" every few rounds, and while my other teams have been "stronger" I know that I've never really worried about a fight I went into with Mortred after the debuffs land.
