What is this client?

You had one job, one fricking job, you can't even get that right. I was one of the few lucky ones that had a bug free client for 2 years straight. Since a few days ago, the client just doesn't work, doesn't create lobbies, disconnects itself from the chat, pops messages that my internet connection is down and all that stuff! I'm trying hard not to swear in this post because I know what kind of so-called people you are. You know that this client just doesn't work, you know that the old client worked every time! Don't be fooled Riot, you don't have a legacy, you had a legacy, you destroyed it not for any reason but for the sake of change, but change is bad... You know what they say "If it ain't broke, don't fix it", well they say it for a reason.. Sayonara
