Well to be a healer first you have to get some good damage making ninjas. That time will come <:3_48:>
And do not underestimate Azure Fangs ability to crit and cause chaos - sure it don't do that much damage as other classes, but you can totally mess up the opponent team. Using standard healing skill (not mystery one) is more that enough more of the time (well not always - one must adapt xD )
i've messed up a lot of teams early on with her as a damage dealer. i know exactly whatcha mean!
