So apparently having a bad game is reportable.

I am so sick of seeing players harass someone because theyve had a bad game. I wish there was a system to punish people who do this... Its so bad when someone constantly flames a 0/3 mid laner because its his promos. You need to understand that Flaming and being toxic is not going to make that player perform better. This system gets abused especially in duoq, If a duo does not like you for ANY reason.. you can -tee youre getting reported for the reason of their choosing and there is nothing you can do but accept the automated warning/punishment. For all the people crying for reports on someone having a bad game.. Please show me the option where it says "had a bad game". Until there is an option to do so, just stop.

TL;DR Flaming someone during a bad game will not help them improve neither will report calling. Just help each other.
