no, that's exactly what he's talking about. thhere are systems in place that dont involve using phrases or statements that cause someone to be perma'd.
refusing to see other options doesn't mean: they don't exist.
if you sit quietly through the game, mute people that are verbally toxic, and report people at the end of the game, you would never be perma'd and a good portion of the people you report, that, based off every peice of information which riot has, will be dealt with based on the severity and frequency of their actions.
**bottom line, you don't get perma'd for being upset, you get perma'd for taking it out on others using riots platform.
**
riot doesnt care about the cause, just the effect.
my suggestion, get a stress ball.
