While I'm not saying you're wrong, I think the main reason for our "beloved" LoL Meta is simple: the players.

Say you look up wiki, think about the Champions abilities and have the idea to use them in an unusual way (like I did with my Support Ez), unless you're a popular player and publish it somewhere, get a ton of nice comments and what not: you get flamed to hell and back. Most of the times your teammates wont even let you play it, troll you or leave. That's even in Unranked Games - I dont want to imagine how it's in Ranked ones.

LoL Champs are reasonably similar when it comes to the scalings/abilities, it's mostly the players that put on the Badges and accept nothing else.
