I had a tank on my team that went 0-11 on Rialto. Rank range was plat 3 - diamond 5. He played the Roadhog mirror for a bit but got hopelessly diffed, we even banned Ana for him. I don't think he was intentionally feeding but I've never seen a tank with that many deaths have 0 kills, how are you not even gonna get an assist? I reported him just in case.
