RPG
Wouldn't it be cool if LoL, bad a short RPG, for each character? They could be just the backstories or lore of each champion. It would be a good way to get people to know their champions better, or maybe even learn something new. Also to teach newbies what they'll be getting themselves into when trying to decided what champion to use. It would interesting, knowledgeable, nice change of pass from the MMO, and most importantly, fun. ( more maybe a some kinda ahh.. noble kinda deals, where voice actors can do the noble for the champion they voiced for in LoL..)
