@Riot: What would you do to design a Voodoo-centric Champion?
The fact that League doesn't have a Voodoo Champion at the moment strikes me as... odd. Is it a stereotype you tried to avoid due to "THAT'S RACIST!" feedback fears? I don't think that's as much of an issue anymore since Lucian has been introduced.
Anyhow, in making a Voodoo Champion, what road would you take? Would you go something along the lines of Doctor Facilier from The Princess and the Frog?

Or would you go something less human, but still Voodoo? Something like Tiki Tong from Donkey Kong Country Returns?

Or perhaps you might try something I haven't thought of.
