New client is a turd

Never used to have problems with the old client. Since the new one came out I've had nothing but problems with it. Just in the past month alone I've had to delete/re-install league of legends 3 times. I've had my play button greyed out for no reason...I've had the client just decide to not open and give me error messages for no reason...I've had games crash and then afterward my client is all bugged and doesn't work properly...I've had the client tell me I don't have an internet connection (which wasn't the case at all b\c every other game I have worked). So I've decided to re-install league (again) and not download the new client. I'll just wait until I'm absolutely forced to use it. Hopefully by then the p.o.s. works correctly
