Meta is an emergent thing. Even if you prevented people from interacting somehow, except through a game, the solutions that work would be found and used. In League of Legends, the 1 top, 1, mid, 2 bot 1 jungler (5 lanes) meta exists because it's the most efficient way to deal with the map and objectives at hand. The double bot is there to better protect the dragon objective, the other lanes being singular makes most effective use of the minions and gold at hand. The use of a single Carry an a single Support for bot is to ensure you have one powerful champion with one weaker champ, that has the utilities to "line up" kills for your carrying champions. This is true for many games. In strategy, there's usually harass (denying your opponent the valuable early game resources), offense (attacking early enough to pressurize your enemy into defence, giving greater map control to you), defence (winning through losing less than your opponent) and an expansion rush (to get a greater amount of resources early at the expense of safety). Throughout RTS games this does not vary a whole lot, though the units used to do so can be varied. The meta (though there can be multiple metas) is what emerges as the "most playable form of the game". You can be for or against it, but in the end it will always happen. Unless you forbid people from playing it at all. The only way to "deal" with it is to keep changing the game so the (or multiple) ideal way(s) of playing the game changes.
