Easiest way to lose your tanks

I’m a healer/tank main that’s been primarily tank in Quick Play or Ranked for the past couple seasons. I’m lord with Devil Dino, Lord with Peni, picking up Strange and Thing, decent at both (I’m still learning). A couple matches ago in QP me and my duo had a Rocket who just wouldn’t stop spamming the fall back ping every two or three seconds, this went on for the entire fucking match, I shit you not. After first round my duo asks him to please stop since he’s hurting the team’s ears. He does not stop. I type “Rocket for the love of god” in chat, and again he does not stop. I was doing very well as Thing, I had the Ace, I was pushing but not going too far from my team, I was getting good kills, but the pinging was starting to seriously piss me off and we had asked him to stop, which went ignored even after I typed in match chat that he was being annoying and wouldn’t stop pinging. So I swap off tank and go Jeff, pocketing the rest of the team except for Rocket and our other tank also swapped off tank and went Spidey (who he had Lord with and quickly stole the ace). Rocket is still pinging every couple seconds. I solo ult him out of frustration, since he refuses to be up with the rest of the team and keeps spamming fall back. I could’ve gotten a team wipe but I’m overstimulated and furious. Before I got on, our car broke down and we had to spend half an hour sweating our asses off waiting for a tow truck, AC on full blast but not really helping. After we got towed to the repair shop and got everything in order, we then had to walk the rest of the way home in 106° heat, for another twenty minutes. I got on Rivals to wind down. Had a couple great matches as Thing, things started to look up for me with the shit day I was having, and then that stupid fucking Rocket just struck a nerve. I don’t normally throw or ult teammates. Generally when I play, I play to win, I watch my backline as tank, pocket the team as healer, if I win that’s great! If I lose I’m not too bothered. But holy shit I just had to rant a bit because even without having a shitty day first, someone spamming pings will overstimulate me and make me half ass the match out of frustration.
