I (try to) play LoL anywhere from once a day to a few times per week. Lately less.
Every time I decide to get on and play, I'm immediately met with some bullshit. Either the enemy team bans my champ, my own team bans my champ, dodges upon dodges, eternal queues, my team starts flaming, etc. I'll watch a youtube video and remember that League can sometimes be fun, then immediately remember oh not really.
And when you run into the strangely common team-banners, Riot never follows up on the reports. Unless someone is literally running down mid and spamming the chat with naughty buzzwords, you will never get any report feedback.
This all happens in normals and rank just makes everything worse with higher pressure.
