@Meddler: I honestly wish Annie (or a new Champion) were more like Rexxar in HotS
Rexxar's always got his bear Misha out, giving him a great ability to 2v1 most enemies even in early game. Annie, on the other hand, only pulls out Tibbers for her ultimate. Feels kinda like League has no true Pet Champion, since the game only has Champions that summon a pet for a limited time rather than having a permanent pet.
I'm gonna assume there's no Perma-Pet Champion because of either balance issues or tech limitations, but it's still something we're missing.
