Stop sweating in quick play

I decided to play some quick play, you know didn't want to play ranked and wanted to play some not so good characters (Ironman) and some guy was using Hawkeye. That's right using one of the best characters that can one shot and was clearly trying really hard. I asked him why he needed to play the meta in casual and he said "shut up when you're using ironman" then I got targeted by their entire team for that so that was awesome and then they said I was bad because of my admittedly low K/D (they targeted me and I wasn't using the meta character) so yeah just wanted to say if you want to try hard please go play ranked
