That is your choice entirely. But just like other battle royals have 1man squad option, why should this be different? After all, it's up to you to get better and how you choose to challenge yourself.

Oh, I feel you. I think it has to do with some sort of "refresh" that happens when you get back in the lobby. God forbid you get disconnected: everything resets to trios + fill when you get back in the game, and if you forget to untick or change, you're stuck (Stepbro!) like that.
And sometimes, even if you check them, they don't work.
From what I've noticed, complete lack of functionality only happened when first launching the game or after reconnecting (due to error post-game or afk in lobby)
