Annie Stun with Ult Out Of Control
We all know that Annie stun every 4 abilities.All players who play with Annie save their stun for Ult,Because it stun all units in area instant.Here is what was i am thinking.Just like you did with Veigar Event Horizon(W) ability i think Annie's ult need to be the same witch is to not ult instant,Annie's ult need 0.5 or 0.75 seconds delay until the bear show up.
I am just saying that her ult need 0.5 to use so enemy can flash or do something .It doesn't make any sense when Annie throw her teddy and turn into a bear instant.
