V6.9

P : Pyromania

    The current stacks are displayed beneath Annie's overhead health bar, similar to Jhin Jhin's ammunition. 

W : Incinerate

Bug Fix: Annie should no longer damage enemies who escape the area during the cast time. Note that if you escape the area in the same instant the ability resolves - it will still damage you, as with all other abilities.

    Range increased to 625 from 560. 

E: Molten Shield

    Duration reduced to 2.5 seconds from 5.
    Damage return on being attacked increased to 30 / 45 / 60 / 75 / 90 from 20 / 30 / 40 / 50 / 60.
    Damage return ratio increased to (+ 30% AP) from (+ 20% AP).
    Removed: Movement speed on Tibbers.
    Removed: Armor and Magic resistance.
    New Effect: Now grants 16 / 22 / 28 / 34 / 40% damage reduction. 

Summon Tibbers Initial damage reduced to 150 / 275 / 400 from 175 / 300 / 425. Initial damage AP ratio reduced to 65% AP from 80% AP. Burn damage reduced to 10 / 15 / 20 from 20 / 30 / 40. Burn damage AP ratio reduced to 10% AP from 20% AP. Tibbers Tibbers' on-hit damage reduced to 50 / 75 / 100 from 80 / 105 / 130. Tibbers Tibbers' on-hit damage now scales with 15% AP. Tibbers Tibbers' attack range increased to 150 from 125.

    New Effect - Enrage: Tibbers gains 275% attack speed and 100% movement speed that decays over 3 seconds, as well as the ability to ignore unit collision, upon being summoned, when Annie dies and when she stuns a champion with Pyromania.png Pyromania.

    New Effect: Tibbers will now persist after Annie's death. Tibbers must remain within 1200 units of Annie's body and will first prioritize her killer, then low health enemies (champions over minions).

    New Effect: Tibbers will now regenerate 10% of his maximum health every second if he's been out of combat for at least 5 seconds.

    New Effect: Tibbers restores 50% of his missing health when Annie dies, but then loses health periodically.

    New Effect: Tibbers now utilizes the large monster health bar instead of a minion health bar.

    AI improvements:
        Target reacquisition after being disabled.
        Target prioritization
        Longer leash range
        Annie can target herself to have him return to following her.

Honestly the way to make annie less frustrating to play against is to make it impossible for her to hold onto her stacks, like how Vlad can't hold onto his empowered Q. If Annie had to use her stun within 2 seconds or lose it, she'd actually have periods where she's weaker.

Either that or let Vlad sit on his double damage Q indefinitely- for consistency's sake, since both are about as punishing to get hit by early.

As of 6.9 it has a 0.25s animation (and Tibbers) already. The ability's fine on its own and good Annie players W+ flash if they want instant stuns anyway.
