is she also supposed to have an idle animations because she is as still as a rock?
On the topic of voice line issues iv noticed characters warn you about being too far in a lane on your own but these voice lines volume is incredibly low and almost unnoticeable unless there is no minions firing and your still.
UPDATE: In the last game I played she said exactly one voice line. It happened when I killed Gray Talon in the lane. It also sounded like a new voiceline but I might have been wrong. She said no other voicelines throughout the whole game, not even when I killed Gray Talon later in the game.
