Piety Out of Control

Hi there, thanks for your feedback.
We're aware that there's an unfortunate overlap in Piety's lightning skillset, in that both the Ball Lightning skill and Arc excel at hitting multiple targets, thus being good aginst minion players.
We do intent to replace Arc with another lightning spell once we have time to make a new appropriate one, but for now have to work with what we have - the "Lightning Storm" (reskinned firestorm) skill was added the day before open beta, as my suggestion for something different we could do without having time to make new art assets or complicated skill code.
We're quite happy with how that one turned out as something different from the arc and ball lightning, but when we have time to plan out and create new skills for her to use, we'll be able to make both fights with Piety more varied by replacing Arc with something else that probably doesn't do best against small groups of enemies.
