Meta

Why is there even a meta I mean all I see is jhin and varus now.. there is no variety I feel like less now than before with lethality and I think its stupid. Even builds are one way now it seems. Some items are just useless to build. Why is that? If I play an out of meta champ I get raged at, its honestly not that much fun anymore when you get raged for playing out of meta. I know some champs are gonna be stronger but, this is really dumb how I only see two adcs played ever..and they all build the exact same way. I don't know I guess I liked this game when at least I thought we had more variety.
