Sick of being banned due to Riot's inability to make a stable client

I love league, I usually play around 2-5 hours a day, but when my account is banned because the client lags out of a game not once but TWICE in one ranked game causing me to have to restart my computer, I think my relationship with league might be over. I'm sick of only playing norms for fear of having my account banned due to the world's most dodgiest client randomly closing. Norms I never have this issue, only in ranked. So I'm done playing a game where an external force like my ISP or Riot's dodgy servers/client can cause my account to be banned. It was fun while it lasted.
