Whaaaaaat??? I don't have Karma, Anya, Anelia, Clissa, Cornelia or Estelle, among a number of others
This is actually a very good idea for people who lack sufficient ranged dps to burn him down before he gets too far (range can be an issue, and if you take too long and other units start coming in, targeting priority can mess you up, so slowing him down with free cannon fodder is good)
This is also a valid point. I didn't not score Fuuka (yet anyways) but she seems like an intriguing unit.
