Client Crash.... 5 game ban...TY RIOT!

Updated to the new client and a myriad of issues ensued. I attempted to run the client in low spec mode, thinking it would help. To no avail. Reverted to the legacy client to played ranked matches, only to have the client crash repeatedly, now i have a 5 game low priority queue penalty. Thanks Riot for poor workmanship on developing the client, in the future, system test and verify before launching a substandard product.
