So my client works fine, it is whenever I enter the game it simply doesn't connect for some reason. Honestly, the issues I've been having with the client this patch makes me want to quit this game.
So far today ranked was broken, kept having weak connection for duration of each game even though my internet was and is working fine to now not being able to connect at all. This also excludes some UI issues, crashes, input lag and champion select glitching (not selecting bans, randomly booting me out and simply throwing me back again when the game is about to start) that were present throughout the week.
This patch has been the most obnoxious so far, including the meta changes they did.
