why league client isn't balanced

In the beginning of league of legends was fun because it was a new and fresh perspective on a well loved genera being a MOBA. In recent years they have tried to revamp the game by reworks and quality of life buffs. Some of these changes were in the client, like low priority ques for afk/ rage quitters. I have ran into the problem of the lol client legit crashing in the background of the game, i checked and it said i was fine, it was the client corrupting (server side error) then forcing me to force restart my computer and then trying to load back into the game. When I came back 7 mins later (due to the league client legit giving me multiple lag spikes and client freezes)(And before you say upgrade your comp or internet i'm running a bang and olufsen i7 2017) and the internet I have is the best physically possible) thinking OK maybe salvageable, it was not, after the game ended i wrongfully received 5, 5 minute time bans. do you believe under the circumstances that this is a viable way to resolve issues with afk/ragequit (im not gonna argue to get them resolved it would be nice so i dont have to sit in 17 min queues 5 times) or do you believe it adds to the toxicity of the game
