Playing Ranked/Competitive game modes comes with the implicit contract to your teammates that you try your best and play in good faith. I don't think necessarily you have to follow the meta. But it's like best practices. Better stay within them when you are playing with a completely new team. There's other game modes in all those games to try wacky stuff and/or play just for fun it's unranked/casual and custom game modes. You wouldn't sign up for a ranked league in real life to just mess around. It would be disrespectful to your teammates and you would rightly get kicked.
