I really love the idea, i've been into fantasy football (NFL) for a while and also wanted to enter the new LoL fantasy stuff. I dont have much time to think about criticism or special ideas but i would advise you to have a look at vulcun(.com) they are the best website for fantasy LoL and it may give you an idea or 2 for the class issues concidering that league has 5 different roles to play. Also the system with the paid league and free leagues seems interessting although we obviously lack the manpower for a lot of paid leagues with high prices.
Anyhow, such an awesome idea !

For sure its legit !! Love the effort !

Think it's a tad bit heavy on the intuitive and maybe on the feeling but other than that its quite accurate, crazy...

You have never seen sideshow play medic have you ? If he was our backup med we could just forfeit every game he'd play in.
