Bring back "Unskilled player" report option...
...but have absolutely no weight added to it.
Just make it a box that someone can click in the report if they get upset that someone on their team isn't doing well. It won't be sent as a report, it won't even show up to anyone, it will just be there for eye candy.
Then, crack down on toxic behavior towards those who flame people who are doing poorly, and refer them to that report button.
When it was still a report category, if I was ever mad at someone for doing poorly, I often times just told them "reporting you for unskilled". Still wrong, but I was new and didn't understand yet. Clicking the "unskilled player" box made me feel a lot better than I would have if I had just flamed them. I think and hope that it's the same way for everyone else.
Should this be implemented? Tell me what you guys think.
