DJ Sona Idle animations, bugged or intended?

DJ Sona's concussive and Ethereal idle animations don't match the teaser which isn't really a problem for concussive but Ethereal looks really boring with her standing there doing nothing while the other stances have alot of animations and energy. I get that Ethereal is supposed to be the calm and soothing stance out of the three but her idle animation in the teaser was so good (holding helmet with both hands and bopping back and forth)
