Connection problems
I've felt that since the complicated Azir release, the number of connection issues has increased significantly. While there have always been the occasional internet-related lag and D/C problems, afer Azir came out it seems like at least 3 of 5 games either have a player severely lagging and leaving games. The problem with this new LeaverBuster is that with the increased number of D/C's, players will be penalized for the clients shortcomings. I myself have experienced plenty of time since Azir's release the frustration of D/Cing only to receive the infamous firewall error message (which is always an issue with the game, never one with my PC) when I try to reconnect. Now, with the release of patch 4.20 (ayyyye), there are the new problems with logging in and not being able to connect to chat in lobby. Starting up the client is taking longer than ever and when you finally get in, the chat doesn't work unless you exit the game and restart it at least 4 times. I understand that there are a million different files that could potentially get messed up but it's just crazy how with the release of a new champion, we can now always expect tons of new quality issues.
