How come so many people don't consider Chasca as a top tier DPS?

Even at C0, her ability to clear a 12th level abyss room is astonishing. And more importantly, there's almost no tricks necessary to reach her damage ceiling. You don't have to worry about timing, nor doing attack dashes. You just activate her skill, hold attack, and point to the general direction where enemies are at. In that regard, she's on par with Neuvillette on easiness of use.

But when people talk about top tier DPS, it's always Maviuika, Arlecchino, Neuvilette. Many rankings even had her behind Mualani or Kinich.
