I think Annie's damage is to high
Relative to how much skill it takes to play her.
I think she needs some slight nerfs. She is one if the easier (easiest in my biased opinion) champs in the game, yet gets pretty famed high amounts of damage when she's all point and click.
I have nothing against point and click champs, but Annie has almost zero downsides besides mobility, and this isn't enough.
She also generally builds road, which is a strong item, and is much more durable then many other mages.
She has an easily accessible stun, and a companion who really hurts.
All I see from her is upsides and mass damage. I personally feel like its a bit TOO much damage co side ring how easy she is to play.
