[2021] LS on why riot should add professional play to the client

So I know it's not the most visible location (definitely pretty deep in the client), but if you go to the Ranked tab inside the profile, and filter the ladder by "Top Solo/Duo Players" you can spectate games in progress from the top solo queue players if they have a "spectate eye" next to their name.

You just right click on the name and click `Spectate Game`.
