How to fix annie.

Annie doesn't scale very well because of her meh burst, lame sustained damage and moderate risk vs lowish reward. She needs to close out games fast but can't kill towers quick enough to contribute all that much to doing so. Also, smite and the like melt tibbers. I propose making Tibbers like a mega rift herald, giving him 10000 health, keeping his damage to champions the same and making him do 4 and a half times normal damage to towers / let his aura work on towers. This will make dying to annie in lane slightly more punishing and give her team something to group around. Thoughts?
