I think that's why I like prerelease (and sealed, generally) the most of any format. For day 1 prerelease, a lot of the players are reading the cards for the first time. For sealed later on, even if you know the meta for that set, it's more about playing the best deck with the cards you've got. Knowing the meta doesn't change your pool. (As opposed to draft, where if you don't know the meta you might inadvertently pass excellent cards and miss signposts other players will catch)

This is why I primarily play Old School 93/94 and other non-rotating, niche formats.

The player bases are a lot more "chill" overall, despite still being attracted to playing their best.

Well playing Fortnite is the opposite. If you suck you get into crappy pools. Every once and a while it someone resets and you spend a few matches getting victory royale until the competition gets better. Way more fun for everyone this way.
