Can Annie get a decay on her passive if she doesn't use it now?
Why is it that there are variations of power that are lost when you don't do anything with it.

have some sort of mechanic that decays if they don't keep up with the demand.
And riot loving to have champions have frames of power.
So why is it that
can sit on her passive and wait for the one time you mess up and die for it... making it one of the few champions that go against this.
So would having her passive decay say like a
reload be out of the question? 10 seconds and she loses her stacks, making her have to utilize her passive in a short time after getting it or lose the power it has.
With the assassin rework riot is making it so assassins have specific time frames of power and if they don't utilize it, they lose the potency.So why not give her something to raise her skill bar while not touching her damage?
need to spend mana and spells to stack up. Also there are cool downs associated as opposed to the champs above which can auto frequently.
