Can you please fix Kalista's ult knock-up animation?

Since her release, Kalista's knock-up animation from her ult has not matched the actual knock-up duration. This is incredibly misleading because the enemy lands, but they still can't do anything because they are still airborne for a good second after they land on the ground. You already have Janna max q knock-up animation, which is the same duration, but you still haven't changed it.
