As a beta player, Riot is easily one of the most incompetent developers ever.
The reason they're bit is 100% pure luck. They had the right game, aimed at the right demographic, at exactly the right time. If League was launched today it would be laughed at for how many missing features it has
Replays were promised on game launch. That was 5 years ago.
They changed their champion pricing schematic from "Hardest champions cost more" to "New champions cost more" the MOMENT they started getting popular.
They changed their IP gain formula, so that players would earn less, then bold-face lied with incredibly misleading graphs designed to lie with numbers.
They waited to nerf Pantheon until after his new skin launched.
And of course they've been telling the community WHAT THEY'RE SUPPOSED TO WANT since the beginning.
I used to defend Riot to the death, they're a really sad company that doesn't deserve their success.
