No, it's not. Short of a player I encountered a few days ago, who got so mad at another teammate he was arguing with and literally typed the words "I could just sit here and do nothing" and then picked Mercy and sat outside the cap point and did nothing (literally stood there afk) there's nothing you can report a player for based on picks. Mercy can shoot, which means she's not healing, but she is doing something, so not a report offense. Lucio can speed boost his team when not healing and shoot while still contributing. Yes, almost every person that plays the game would agree that these style players are not playing right and throwing the game; however, they are still playing. Bullshit or not, it is what it is.
