How about saving all client settings online rather than on our computers?
I just did the thing you recommended, unpinning league from the task bar and repairing the client. It didn't delete my custom item sets as was stated. What it did was resetting all changes i made in the client like music during select, notifications, esport notifications, language filters and all that stuff. it would be easy to have a "save settings" "load settings" thing in the client or better yet, store that info online to make it independent from anything we do on the computer. Please make it so, @Riot
