This feels suspicious to me. Staying alive during a double-pull is a legitimate test of skill and teamwork for both the tank and the healer, so that's easy to believe. But the part about boss fights...I'm respectfully scratching my head. Do you have trouble staying alive as other roles as well? Because of all the roles, tank has the easiest job surviving in a normal mode boss fight due to their innate durability.
That being the case, I'd like to hear more about what's happening when you're dying in dungeon boss fights as a tank.
Though even without additional information, you're not going to get banned for being bad at the game. That's nothing you need to worry about.
