Annie support build

I've been using as support. I don't think she's super good in that role, but I think she does a good job countering certain champions like and non standard bottom choices.

After playing some games it feels like going AP build on her doesn't work. Most of her abilities have short range, and that means she's going to get dog-piled by the bad guys. To keep her alive and kicking I've been going into , and then going into straight tank stats (depending on bad guy comp it varies what I build into). It seems to work much better, since I can normally open with a tibbers stun with ability spam, and I can usually live long enough to get to a second stun even when I get dog piled.

Is there a better way to go about this, other than not playing her at all?
