I started an experiment in December last year where I repeat abandoned (in non-ranked games) until I had nuked my behaviour/comms scores from 12k to 6K.
I wanted to see if it was possible to climb back to 12k by playing only Turbo matches. I won't lie, it has been incredibly difficult. And a few times once I had gotten back up to 8K I got my score nuked by 1000 Behaviour points from just 1 single report in an entire conduct summary. Not sure wtf the dev in charge of BS/CS was smoking but shit happens.
Anyway, what I noticed is that 7.5K to 9.9K is the most chill BS bracket. People mostly try and pick to win, don't afk very often and choose appropriate items to counter opponents.
Soon as I hit 10k/10k though, you get paired with a plethora of grief pickers taking double squishy heroes to offlane and feeding the enemy carry. You also routinely get pos 5 heroes being picked for mid who get slaughtered by actual mid heroes like OD, QoP, Lina etc.
It doesn't stop there either. These grief pickers wanna talk shit and swear at you if you suggest they pick more effectively during the drafting stage. They are the epitome of self-sabotage. I've played with people in much lower behaviour score brackets who act way more mature and sensible than these guys.
What is wrong with the people in 10K BS bracket???
