Annie Rework Idea?

Seems pretty viable to me, and not as op as as the currently small amount of counterplay she has now.

Now for the actual rework...

Passive: Pyromania Flames Within

Every time Annie casts Disintegrate or Incinerate on an enemy, she gains a stack of Rising Power. Every stack of Rising Power increases Annie's total Ability Power by 3%/4%/5% (increases every five levels). Annie can have up to ten stacks of Rising Power at a time, for a total of 30%/40%/50% extra Ability Power. If Annie is out of combat for 5/7/9 seconds (increases every five levels), she will lose stacks at a rate of one stack per second.

Q - Disintegrate Cooldown 4 6 seconds Reduce AP Ratio to 60% Add a 40%/45%/50%/55%/60% 1.5 second slow.

W- Incinerate Cooldown 8 10 seconds Reduce AP Ratio to 65% Gives one stack of Rising Power, plus another stack for every enemy champion affected if two or more champions are affected. (Hitting one champion will give one stack total, hitting two will give two stacks, and so on)

E- Molten Shield

Remove all current effects, 20 second cooldown and 50/60/70/80/90 mana cost.

Places a shield around Annie for up to five seconds, and give Annie 5%/10%/15%/20%/25% temporary cooldown reduction (can surpass the current cooldown reduction limit). This cooldown reduction only affects Disintegrate and Incinerate. During the time that this shield is active, casting a spell will cost double mana. The shield can block 25/50/75/100/125 (+60% AP) damage, and destroying the shield will remove all of the other effects of it. The shield barrier amount is increased by 15% for each stack of Rising Power that Annie has before casting Molten Shield.

R- Summon: Tibbers

Annie releases her bear Tibbers from his toy prison, dealing 175 / 300 / 425 (+60% of ability power) magic damage to enemy units in the summon area. For a limited time of 45 seconds, Tibbers can move and attack at Annie's will, while continually dealing 20 / 30 / 40 (+20% of ability power) magic damage to surrounding enemies.

Tibbers has 1200 / 2100 / 3000 health, 30 / 50 / 70 armor, 25 / 45 / 65 magic resist and 80 / 105 / 130 attack damage.

(Same as before, except a reduced AP Ratio)

If Annie has ten stacks of Rising Power before casting Summon: Tibbers, Tibbers will become empowered, and will consume all of Annie's Rising Power stacks. On cast, he will stun all nearby enemies for 1.5/1.75/2 seconds, and give them Nearsight for half that duration. Empowered Tibbers will have 150 extra movement speed, and 100 extra attack range (big flaming claws).

Hope you like it... seems slightly more balanced than Annie's current state.
