Meta means more when everyone in the game is highly skilled.
But even then breaking meta is not auto lose. The meta is how it is because it is the strategy that is generally acknowledged as the "better" strategy to use. But some new unheard of composition might be much better and simply hasn't been tried and tested yet.
I'm not saying you should do random stuff every game, just don't be that person who breaks a gasket during champ select because someone picked a champion you don't agree with. Call them an idiot after the game if you want of course.
