Client

I've had issues the past couple months with accepting the AFK checker before champion select. When playing with friends, I don't get the AFK checker prompted when my friends do; the client keeps searching for games. When playing alone, I know I won't get the AFK checker prompted when the queue time is 2x the expected queue time. Some time later, I'll get a message telling me that I've failed to accept the AFK checker. In champion select, champion bans and picks will often lag anywhere from 1 to 5 people behind. This often causes me to dodge for failure to select champion. Often, whenever I click on a champion in champion select, the client will just crash without warning or any sign of crashing other than the client being closed. All of these issues have caused my account to get banned, and now I am for the second time placed in low priority queue with 20min waits in between games for dodging. I would love some help on how to fix these issues and if possible a repeal on the bans. I think the chat history between my friends, in champion select, and in game would be sufficient proof of the occurrence of at least two of these issues.

Greater chance of the first two issues occurring on the new client, but the legacy client is the only client to experience problem 3.
