New kind of champion which has a permanent pet

I've got an idea of new champion. I heard that you're goin' to make a champion which have permanent pet system(unlike Malzahar's voidling or Annie's bear).And I thought of Evan of Maplestory (http://maplestory.nexon.net/game/classes-and-jobs/2890/evan) I mean what is cooler than a dragon and it grows when level up. Maybe you won't take the whole idea of Evan. But I really think that a pet that can grow is a great idea,and I suppose that you can make it with the tech you got now. I thought that a great idea should never die. I'm a Taiwanese player
