League client super buggy/friendlist buggy/messaging buggy

League client needs to be fix for its super laggy. I have a super good PC and its laggy/freezing 60% of the time. Friend list also needs to be fix for it always say people are in game but they're actually not. Messaging is also a problem, sometimes my friends can't receive the message and then minutes later they receive it. This needs to be fix! I'm not sure if other people are experiencing the same thing but me and my friends are experiencing this super badly and it's getting really annoying. Fix t please riot!!!
