Most of League's champions fall into certain factions: Demacia, Noxus, Piltover, and others. However, I noticed that a couple of champions didn't go were I thought they'd go.
Fiddlesticks
Fiddlesticks was the first one that caught my eye. He's a scary guy, but he's not from the Shadow Isles. Fiddlesticks is a being summoned from another world who sits underneath the Institute of War. Wouldn't it make more sense if Fiddle was a Shadow Isles guy like 
Thresh, 
Hecarim, and 
Yorick?
Maokai
Maokai's lore says that he's from the Twisted Treeline , but that was before TT changed into the Shadow Isles. He's a magic tree that hates wizards, but that doesn't really fit the Shadow Isles theme. Perhaps it would make more sense if he were from the Kumungu Jungle like 
Nidalee or 
Zyra.
Nocturne
Nocturne, like Maokai, was from the old Twisted Treeline. Sure, Noc is a scary guy and he could fit in on the Shadow Isles, but what if Nocturne was a Void champion like 
Cho'Gath, 
Kog'Maw, and 
Kha'Zix. Nocturne was originally from another world, and he embraces the darkness (or the void).
Shaco
Shaco's lore doesn't really say where he's from. Where would a Demon Jester come from anyways? Zaun is the only place that comes to mind, and I think he'd fit in with 
Dr. Mundo and 
Singed.
Good ideas, or am I just crazy?
