What file does "Force Taking Role" Go under?

Griefing/Assisting enemy team is where I file it, because it creates in-fighting. Other people put it under Negative attitude. Either way you should write a note in the comment box to explain exactly what happened.

Did he actually go top? Or are you saying he just picked a non-meta support?

If he didn't actually run down a lane he wasn't assigned all game, he didn't force steal it, you gave it up to him.
