Why don't more people use the Legendary Client?

If you haven't heard of the Legendary Client you should take a look at this video. https://www.youtube.com/watch?v=rVWdHeQcGwM&ab_channel=EdV

(The client is somewhat outdated in the video but it's still relevant)

The client has an auto-queue acceptor, a live game scout, informing you of current in-game stats which is helpful if you have multiple monitors like me, an easy way to install custom HUDs, a background to the client that you can choose, custom colors, and it even tells you your ping before starting a match.

I honestly like it more than the original client, it has bugs, but so does Riot's.
