The option to reduce the cost of a skill you already had doesn't work. It said something about reducing the cost by -9. Instead it just knocked my mana down to -9 when I used the skill
Add a class that has more control / denial aspects. I was thinking something like an Ultimate Ability that allows you to hypnotize and then use one of the other team's characters for a turn. I was thinking Dracula / vampires, but I like the idea of normal characters that could be in a neighborhood. Maybe a psychotherapist.
