Tanking the toxicity, a tanks struggle.

Doing some arena/angerforge runs on Dreamscythe tonight and a mage starts complaining out of nowhere after i taunt resisted on angerforge and my sunders kept getting blocked. Could I have played it better? Yes. We go on to kill it and mage tells me to unalive afterward in pms. Like even when nothing goes wrong people will still complain even when everything is going fine. I just dont understand the needless toxicity. How sad are you that the moment something doesnt go absolutely perfectly in your video game that you then feel the need to tell people to kill themselves... And people wonder why nobody wants to tank....
