Gotta Say...The Client Stability Is Absolutely Crap Right Now

I've had more problems this patch with the client than in the last 7 years I've been playing this game.

1. My client freezes during the beginning of champ select and does not allow me to select a champ. Randomly either dodges me or somehow picks 'None' during the ban phase and I reconnect 40 seconds later.
2. Alt tabbing during loading causes all of the art to disappear on the loading screen when retabbing into it.
3. While in queue, sometimes if a match is found, the client simply plays a sound 10 seconds after and auto declines for me.

All of these happen frequently. Plz fix...);
