Annie's stun should be like Ryze's shield
Why does Ryze passive wear off if you don't use spells but Annie's stun doesn't? She can just hold it and auto attack you with her high range and you can't do anything or she'll stun you. Ryze can't do that because if he tries to hold his shield at 4 stacks it goes away.

can't keep 2 of his orbs on you and wait to use the 3rd to stun you for more than a few seconds,
