How many games have you played? I’ve played at least a dozen in the last few days that had no tilting in the text chat (or voice chat for my team).
The reason why people tilt is because they are immature and have a weak resolve, giving up at the first sign of adversity.
Ah you are part of the problem in this community. You are spreading false information, there are several heroes that are good from every category, and the Tanks and Supports are actually good.
What is fun to you? Genji or Tracer main I assume?
