Buggy New Client

I updated to the new client and I'm still having the same problems with it not even my friends could explain it and after searching the internet I'm only seeing people have Ms issues with the new client. every time i get into champion select i cant connect to chat just says "connecting..." now my runes are all messed up my top lane runes duplicated itself twice and wont let me swap to any other runes but my top runes. can i please keep old client rito? tbh id rather take the crash on S ranks on champions occasionally then not being able to play and have fun.
