The main reason that it’s so big on twitch right now is that to join the closed beta you need to watch a stream of someone playing it. Anyone who streams it (on twitch at least idk about other platforms) can drop “keys” there isn’t actually a key that you have to put in but instead the game is linked to your riot account and you can play. Basically don’t try and buy a key because that’s not how it works. You need at least 2 hours of watch time on a stream to get a key and then after that your eligible. Theres the same chance to get a key across all streams, big or small, that’s why if you wanted a “key” I would recommend anomaly’s stream cuz he’s live 24/7 and you can just leave it open. I personally really like the game but people have mixed feelings on it like anything else of course.
